Custom Exception Handling: From Chaos to Clean API Responses In Part IV, I built a bulletproof document management system with state machines and atomic operations. But there was still one glaring problem: terrible error messages. When users send malformed requests to your API, FastAPI's default error responses look like this: { "detail": [ { "type": "missing", "loc": ["body", "files"], "msg": "Field required", "input": {"wrong_field": "value"}, "url": "https://errors.pydantic.dev/2.4/v/missing" }, { "type": "string_too_short", "loc": ["body", "name"], "msg": "String should have at least 1 characters", "input": "", "url": "https://errors.pydantic.dev/2.4/v/string_too_short" } ] } This is developer-hostile.

In this post we'll explore the concept of AI agents as software engineers on your development team. The idea that you could write up an enhancement or bug fix and assign it to an AI team member and see what they came up with a short while later would have sounded fantastical only a few years ago, and yet, with the announcement and preview of GitHub Copilot Agents, this is a real technology that exists and you can make use of today. GitHub Copilot Coding Agent is a new technology, currently in preview, associated with GitHub pro and enterprise accounts. With Coding Agents you can assign individual issues in a GitHub repository to GitHub Copilot, just like you were assigning it to a team member. Copilot will then create a branch for your issue, just like a developer would, and begin to plan…  ( 12 min )

Exception generation. You certainly know what this is and have definitely used it, if you've programmed even a little. Here's news for you: exception generation is very often bad. In any situation where a try/except (or try/catch) block is used not for "wrapping" side effects like reading files, going to the network, or in an isolated place around a function (for targeted debugging purposes or simply because "there's just no other way") — it's better to get rid of it. But why? Because such try/except blocks seriously confuse two "processes": Program execution flow Developer's thought flow who will read this code Think about it yourself — any instruction in a try/except block can throw an exception. Does it seem like each such block increases the complexity of our program's execution flow g…  ( 7 min )

1.1 What is Customer Lifetime Value Customer Lifetime Value (CLV), putting in simple terms, is the worth of a customer to a business for the complete period of their relationship, or the total amount of money, a business can expect from the customer during their lifetime. Revenue generated by the customer varies for each customer business pair individually. For a business, a customer might be worth a million, but a second customer might be worth nil, or maybe the first one might worth nil for another business. CLV can be used as a metric of profit associated with a customer-business relationship. A fast way for determining a customer’s profitability and the potential for the company to develop over the long run is to compare the customer lifetime value against the cost of acquiring a new…  ( 27 min )

I'm a frontend developer — mostly React, mostly browser-side. But over time, I've realized that understanding the database side of things isn't just “backend stuff” — it's essential if you want to build better apps, debug faster, or go fullstack when needed. This is not a career switch. I'm not trying to become a backend expert or a database admin. I just want to get decent at PostgreSQL — enough to design schemas, write solid queries, and understand what’s happening under the hood. For the next 30 days, I’ll document my learning process. No filler. Just focused, practical lessons from a frontend developer’s perspective. Let’s see how far I can get. Day 1 starts now. I'm going to use docker for my postgresql install. If you don't have docker installed on your machine, just figure it out! F…  ( 7 min )

Artificial Intelligence (AI) is transforming industries worldwide, from healthcare to finance, and even customer service. However, as AI systems become more prevalent, concerns over fairness, ethics, and transparency continue to rise.

Author: Jared Lunde Let me introduce you to someone: they just released a new app, they started to tell people about it, and now they find themselves checking their Postgres database every 15 minutes to see if anyone has signed up. The thought of setting up Zapier or Mixpanel for a few simple product alerts puts them in physical agony. That was me just a few months ago. Alright, I thought: I’ll write a script, upload it to a Lambda function, and set up an EventBridge schedule to run it every hour. After over two hours of writing CDK, debugging permissions, waiting in the slow CloudFormation loop, and setting up a package to deploy, I finally received a Discord notification. Wahooo!!…? Not really. Because that’s how I spent my entire Saturday morning. Look at this code: import { DiscordN…  ( 7 min )

A intencionalidade é um conceito filosófico central na fenomenologia, definindo-se como a direção da mente a um objeto. Brentano, por exemplo, caracterizou os fenômenos psíquicos exatamente por essa “direção a um objeto” ou “referência a um conteúdo”. Em termos mais simples, toda consciência visa algo fora de si: ela está sempre intencionada a um objeto ou conteúdo. Husserl aprofunda essa ideia afirmando que não há consciência sem objeto: a mente não é um receptáculo passivo, mas um “vazio” que está continuamente voltado para algo externo. Diante disso, surge a pergunta: “como aplicar essa noção à inteligência artificial moderna?” Embora máquinas não tenham consciência em sentido humano, sistemas avançados de IA, especialmente os agentes autônomos, exibem comportamentos que parecem ter “in…  ( 15 min )

Real-time data visualization is tricky. While many tutorials show you how to create basic charts, they often skip over the challenges of handling continuous data streams efficiently. Here's how I built a production-ready solution that handles thousands of data points while maintaining smooth performance.

The Current State of Flutter Logging (It's Bad) I reviewed 50+ Flutter projects on GitHub last week. Want to know what I found?

This article was written by Radhika Sarraf. Modern businesses generate data from countless sources: transactional databases, SaaS applications, IoT sensors, social media platforms, and more. The challenge isn't just collecting this data; it's efficiently extracting, transforming, and loading (ETL) it into a destination that can handle diverse data types and scale with your growing needs. MongoDB is usually preferred as a destination for organizations looking to consolidate their data landscape. Its document-based architecture, flexible schema, and powerful querying capabilities make it ideal for handling the variety and velocity of data demanded by modern applications. However, efficiently transferring data from various sources to MongoDB requires the right ETL tools. This guide explores t…  ( 14 min )

"Can neural networks really compress faces efficiently, without losing identity?" In this post, I explore this question by building and comparing two popular generative compression architectures: Variational Autoencoder (VAE) and Vector Quantized VAE (VQ-VAE) — trained on passport-style human face images. 🔗 GitHub Repository 📂 Dataset Source (Kaggle) Autoencoders learn to reconstruct input data from a compact representation (latent space). This enables lossy compression by: Removing irrelevant pixel-level noise Learning semantic structure (e.g., eyes, nose, face contour) Outputting reconstructions that are visually close to original but much smaller in size But not all autoencoders are created equal. Let’s break down how VAE and VQ-VAE differ — and which one works best for face images. D…  ( 7 min )

The Great Sleep Heist of 2025 Picture this: You're tired, you've got exactly one hour before your next commitment, and you think "I'll just rest my eyes for 5 minutes."

Introduction With the introduction of signals in Angular, many of us are gradually adapting our patterns and habits. For years, RxJS was the default way to handle reactivity in Angular applications. While RxJS is powerful, it often comes with a steep learning curve and verbose code, especially for simple cases. In this article, I’ll walk you through a common scenario: fetching a list. We’ll start with an imperative approach, then refactor it using RxJS for a more declarative and reactive style, and finally simplify it even further using Angular signals. Imagine you have a list of items fetched from an API. You need to: Fetch the list Show it in the UI No pagination, no complex logic — just the basics. This is often how we start: calling HTTP methods and updating local component state ma…  ( 7 min )

Tired of feeling lost with all the machine-learning buzzwords? You’re not alone.

When building a React Native app, ensuring secure authentication is crucial. One popular solution is using JSON Web Tokens (JWT). However, if not implemented correctly, JWT can lead to common pitfalls that compromise the security of your app. In this article, we'll explore the most common JWT pitfalls in React Native and provide tips on how to avoid them. One of the most significant issues with JWT is insecure token storage. It's common to store tokens in local storage or cookies, but this approach is vulnerable to attacks. To avoid this, consider using a secure storage solution like the React Native Keychain. Another common mistake is not verifying the token's signature. Failing to verify the token's signature can lead to token tampering, which can result in unauthorized access to your app. To prevent this, ensure you're verifying the token's signature using a library like jsonwebtoken. Lastly, it's essential to implement a token expiration mechanism to ensure tokens are regularly refreshed. Failing to do so can result in tokens remaining valid for extended periods, compromising the security of your app. To avoid these common JWT pitfalls in React Native, follow these best practices: Store tokens securely using a library like React Native Keychain Verify the token's signature using a library like jsonwebtoken Implement a token expiration mechanism to regularly refresh tokens By following these best practices, you can ensure robust and secure authentication in your React Native app. For more React Native development tips and best practices, check out IAMDevBox.com.

Problem You are given a large integer represented as an integer array digits, where each digits[i] is the ith digit of the integer. The digits are ordered from most significant to least significant in left-to-right order. The large integer does not contain any leading 0's. Increment the large integer by one and return the resulting array of digits. Example 1: Input: digits = [1,2,3] It may look like a simple solution of simply adding 1 to the last number - but you have to account for the number being 9. If this is the case you'd need to carry the 1 and thus incrementing the next number. This "carrying" would need to be done, for all the 9's, so if we had numbers like 999, it would need to be incremented and an extra number added to create [1,0,0,0] So, if the current number is lower than 9, we can simply increment it by 1 and end the loop, returning the array of digits. If it's equal to 9, we set it to 1 and move onto the next digit (i.e carrying the 1 - that then get's added to , and returns the new array). If all numbers are 9, it'll iterate all the way through to the end of the loop, at which point we've handled this eventuality and then add a 1 to the beginning of the array. public int[] PlusOne(int[] digits) { for (int i = digits.Length - 1; i >= 0; i--) { if (digits[i] < 9) { digits[i]++; return digits; } else { digits[i] = 0; } } int[] newDigits = new int[digits.Length + 1]; newDigits[0] = 1; return newDigits; }  ( 7 min )

As many of you probably did, I came across Emmanuel Mumba’s Top 20 Rising GitHub Projects with the Most Stars in 2025. Instead of just bookmarking it, I spent time using collab.dev to explore five projects that felt both practically useful and actively maintained—the ones I could actually imagine adopting in day-to-day dev work. Here’s what I learned that goes beyond the feature lists. Hoppscotch (⭐ 71k) – Postman Without the Weight Hoppscotch feels like what Postman might be if it were rebuilt today: fast, minimal, and open source.

Introduction For more than a year, I've been exploring AI Engineering by observing numerous new startups leveraging AI and launching my own products. AI is a super hot topic, and when you first try to build an AI tool or read about AI applications, it seems like a magical world where completely new principles are applied. But the key thing I learned during this period is that building AI applications is a process that's not too different from building distributed systems where reliability is a mandatory requirement. In this article, I will explain how to build AI applications by applying distributed systems principles to make applications reliable and scalable. Let's consider an example of the simple application: User sends a request to a service Service sends a request to LLM LLM retur…  ( 11 min )

I like staying close to the browser. It already knows how to do a lot - rendering, accessibility, navigation, forms. The more I can lean on that built-in behavior, the less I have to reinvent or debug what the browser already handles well. That’s part of why I’ve always liked tools like Stimulus, Hotwire, and HTMX. They let the browser handle what it’s already good at. But as my projects got more interactive, I started wanting something a little more composable, something that lets me reuse logic cleanly without giving up the simplicity of DOM-first development. That’s the gap HookTML tries to fill. At work, I use React with GraphQL and styled-components. It’s hook-heavy and composable. In my side projects, I was using Rails + Hotwire + Stimulus. And switching between those two mindsets wa…  ( 10 min )

Problem Given the root of a binary tree, return the "inorder traversal" of its node's values. Firstly, you're maybe thinking what is inorder traversal ? Well it means: For each node: Visit the left subtree first Then visit the current node Then visit the right subtree Example: 6 / \ 4 8 / \ \ 3 5 9 / 1 In‑order traversal steps: Start at root 6 → go left to 4 From 4 → go left to 3 From 3 → go left to 1 → visit 1 (no left child) Back to 3 → visit 3 → no right child → back to 4 Visit 4 → go right to 5 → visit 5 → back to 6 Visit 6 → go right to 8 From 8 → no left child → visit 8 → go right to 9 → visit 9 So we go as far left as we can before returning back up the branch and going right, until we try to get left again as far as we can and so on. We achieve this using a Stack which works on a LIFO (last in first out) approach. We keep going left, pushing nodes onto the stack. When you can’t go left anymore, Pop() from the stack, visit the node and move to its right child. Repeat until both current is null and the stack is empty. Whatever result we have at the end is our inorder-traversal of our binary tree. public IList InorderTraversal(TreeNode root) { var result = new List(); var stack = new Stack(); var current = root; while (current != null || stack.Count > 0) { while (current != null) { stack.Push(current); current = current.left; } current = stack.Pop(); result.Add(current.val); current = current.right; } return result.ToArray(); }  ( 7 min )

This article is a machine translation of the contents of the following URL, which I wrote in Japanese: https://qiita.com/Nana_777/items/e53d3e119a3b43a2ad88 In the previous article, we explained how to use the MCP tool with Kiro. [Previous Article] https://dev.to/aws-builders/aws-get-backlog-issues-via-the-mcp-tool-and-have-kiro-fix-them-kiro-59p7 There are many MCP tools available, but if you're looking for AWS-related tools, you can use the "AWS MCP Server" website. https://awslabs.github.io/mcp/ Create a folder on your local PC where you want to clone the MCP tool. git clone https://github.com/awslabs/mcp.git Please configure the MCP tool in Amazon Q Developer using natural language commands as follows. I would like to use the MCP tool in the following folder. Please configure it. C: [Folder path where the MCP tool was GitClone'd] Configuration is complete and the necessary configuration files are generated. Request a response using the MCP tool in Amazon QDeveloper using natural language as shown below. Tell me about AWS Lambda using AWS Documentation MCP Server Answer returned. Since the explanation of AWS Lambda alone cannot completely rule out the possibility that the answer is based on AI-trained data, we will also test the operation using a different MCP tool. Use the AWS Diagram MCP Server to generate an API configuration diagram using AWS Lambda and Amazon API Gateway in Draw.io format (with the .drawio extension). Also generate a PNG image file. The execution result will generate an architecture diagram using AWS icons like the one below, confirming that the MCP tool was used. [Generated Draw.io file] [Generated image] Even complex configuration tasks were completed by using Amazon QDeveloper in natural language. While this article uses an AWS-related MCP tool, the basic configuration steps are similar for other MCP tools. If you find a suitable MCP tool, please try using these steps.  ( 7 min )

Neon is just amazingly fast, serverless PostgreSQL with branching built-in. But after using it for a few months, I just hit a wall. The dashboard wasn't keeping up. It was slow, the queries were stalling, and eventually I just tweeted about it. To their credit, the Neon CEO himself replied, and the team promptly fixed the backend issue. But when I thought about it yesterday, it left me with a thought: Why am I even using a dashboard for this stuff? So, I built an MCP (Model Context Protocol) server using Composio and Claude Code as my client, and it works great. Now, I manage all my Neon projects locally, no clicking things around, no waiting for the dashboard to load, just prompts and a good, reliable speed.

This is Part 2 of the “Hands-on Transformer Deep Dive” series. We’ll walk step-by-step through modern Transformers’ algorithms and components, and build our own LLM from scratch. If you missed Part 1, check it out here. In this article, we dive deep into multi-head attention mechanism, a foundational building block of modern Transformers. We’ll look into four of its variants: MHA, MQA, GQA, and MLA, implement them from scratch with only PyTorch, and discuss their characteristics and pros and cons. Multi-head attention allows the model to capture complex patterns by looking at the data from multiple “perspectives”. While single-head attention computes the attention once over the whole input, multi-head attention splits the model’s total feature dimension across multiple heads and run them …  ( 14 min )

At first, I thought DevOps was only for ops teams or huge companies. But over time, I realized that adopting a few key DevOps practices can seriously improve any developer’s workflow — even on small projects. Here are 5 habits I’ve picked up that save me time, stress, and confusion. 🧪 1. Automate tests from the first commit 📦 2. Keep CI/CD pipelines simple but solid 🔐 3. Never hardcode secrets 🔁 4. Reproduce production locally (as much as possible) 📈 5. Monitor what you deploy 📌 I’m not a full-time DevOps engineer — but bringing these habits into my daily workflow has changed the way I build and ship software. Less firefighting, more control.  ( 6 min )

Time Complexity: O(n) Best Case: O(1) - When the last digit is not 9 (e.g., [1,2,3] → [1,2,4]) We only check one digit and increment it Worst Case: O(n) - When all digits are 9 (e.g., [9,9,9] → [1,0,0,0]) We must iterate through all n digits to set them to 0 Average Case: O(1) - Most numbers don't end in 9, so we typically only process one digit Where n is the number of digits in the input array. - Space Complexity: O(1) or O(n) Best/Average Case: O(1) - When we can modify the input array in-place No extra space needed except for variables Worst Case: O(n) - When all digits are 9 We create a new array of size n+1 - class Solution { public int[] plusOne(int[] digits) { for (int i = digits.length -1; i >= 0; i--) { if (digits[i] < 9) { digits[i] += 1; return digits; } digits[i] = 0; } int[] newArray = new int[digits.length + 1]; newArray[0] = 1; return newArray; } }  ( 5 min )

It usually starts with a few lines of Python and a ChatGPT API key. You add a few lines of context, hit run, and marvel that it responds at all. Then you want it to do something useful. Then reliably. Then without you. That’s when you realize you’re no longer just calling an LLM. You’re building an agent. I spent the last year cobbling together scripts and wrappers, juggling LangChain chains that felt more like house-of-cards than systems, and constantly wondering, “How are people actually shipping this stuff?” I chased patterns that looked elegant in theory but collapsed the moment real users showed up. I built agents that worked perfectly in a notebook and failed spectacularly in production. I kept thinking the next repo, the next tool, the next framework would solve it all. It didn’t.

It was September 2024 and I was in way over my head. I had just completed a DevOps Engineering program (offered by AltSchool Africa) with "moderate" confidence in the skills I had learned during the 12-month stint. I heard of a job opening and thought "why not" and applied. I was given a take-home assessment that looked very similar to my final project at AltSchool. I was so excited. I thought I would crush it and move on to the interview stage. I was SO WRONG.

Hey everyone 👋 If you’ve been working with Terraform for a while, you’ve probably heard people talk about the state file in slightly hushed tones — almost like it’s a mystical object you should never touch.

“System Design isn’t about memorizing terms. It’s about solving one problem and discovering another.” Here’s a complete journey, starting from the first user request and going all the way to a massive, scalable, real-time backend — explained in simple words, step-by-step. Let’s start from the very beginning. The app that users see on their screen (called the client) needs to get data — like products, users, prices — from a server (a remote computer). This is called the Client-Server Architecture. The client asks, the server responds. But now a big question arises… How does the client find the server?

‘King of the Hill’ is back for season 14 on Hulu, and showrunner Saladin K. Patterson’s mission is to keep Hank Hill’s voice as authentic and hilarious as ever—even while updating the comedy for a modern, Disney-owned streamer. After a ten-year stint in Saudi Arabia (yep, that’s where Hank’s been), Patterson leans into the small-town Texas vibe and familiar characters, making sure nothing feels too “rebooty.” The idea to revive Arlen, Texas, actually started at San Francisco Sketch Fest 2017 when creators Mike Judge and Greg Daniels dusted off an old episode for a live read. Since then, Patterson’s been tackling the big “why now?” question, blending original warmth and humor with today’s sensibilities to prove this propane-loving dad still has plenty of fuel left in the tank.  ( 5 min )

Paramount just handed Matt Stone and Trey Parker a reported $1.5 billion to extend South Park for five more years and 50 episodes—a wild price tag that the duo immediately lampooned in Season 27 by roasting everything from Paramount’s $16 million Trump settlement to its Skydance merger. With linear viewership and ad revenue tumbling and Paramount+ still losing money, South Park’s cultural cachet and those savvy digital-rights deals (shout-out to their 2007 ad-sharing pact) are exactly the knockout IP the studio needs right now. Stone and Parker’s forward-thinking digital strategy—free streaming on South Park Studios, record Hulu and WarnerMedia payouts—has built a massive library that racked up billions of minutes viewed even without new episodes. And let’s face it, controversy is their bread and butter: from naked Trump PSAs to Satanic shenanigans, they prove that nothing drives buzz and eyeballs like South Park’s savage satire.  ( 5 min )

The HR tech industry is evolving fast — and so is how platforms price their services. From payroll systems and compliance tools to performance management modules and hiring suites, modern HR SaaS platforms are no longer built on rigid pricing plans. Instead, they’re adopting usage-based pricing — a model that charges customers based on actual platform consumption. But this shift isn't just about revenue. It fundamentally reshapes how we build, meter, and scale HR platforms. Here’s what’s driving the trend in 2025: Modern HR teams deal with shifting employee counts, seasonal hiring, and cross-border operations. They want pricing that scales up (or down) with usage — not per-seat licenses or fixed tiers. Engineering for this requires real-time data tracking and metering tied to usage events …  ( 7 min )

Disney+ started as Disney’s shiny new frontier, but it’s now clear that the firehose of Marvel, Star Wars and Pixar spin-offs has watered down those once-rockstar brands. Kevin Feige even admits the push to weave in every streaming character “devalued” Marvel, with MCU shows and movies like The Marvels, Brave New World and Fantastic Four all underperforming. Star Wars peaked early with The Mandalorian’s second season, then saw each new series lose viewers week by week, and Pixar’s Elio became its biggest box-office flop ever. The net result? Subscribers are finally tuning out (Disney+ just shed 700,000 users in Q1) and Disney’s overall brand value dipped by 5.6%. Experts say the lesson is “less is more”: constant content churn might keep a platform busy, but it leaves fans shrugging instead of lining up. If Disney wants that “special” buzz back, it may need to hit pause on the spin-offs and let its tentpoles once again feel like events.  ( 5 min )

How are strings in Javascript encoded? It might surprise some people that Javascript uses UTF-16 to encode strings. But if your are like me, you might be wondering: how can I convert this to UTF-8? Well today we are going to find out. 🧐 The main focus in this post is on how to convert a UTF-16 string to UTF-8 in Javascript. It is not about how to deal with strings in Javascript because that is a topic all on its own. We will shortly go over Unicode. Further we will discuss the UTF-16 and UTF-8 encoding scheme in so far as we will be needing it for our purpose. Unicode, not to be confused with unicorn — although the are both pretty magical 🦄 — is the de-facto encoding standard for symbols. You can even adopt a character🤘🏻. Unicode is everywhere.

Technical ownership sounds great on paper. It means someone cares. Someone is responsible. Someone knows the system inside out. But like most things in engineering, it comes with tradeoffs. At a previous company, I was the sole owner of two codebases. I'd been hired to rebuild the mobile app into a new framework-originally React-but after some digging, I realized that plan wasn't going to fly. The company pivoted to rebuilding the management console first and revisiting the app later. Eventually, both became my projects. From the ground up. Just me. It got to the point where, during a year-end company speech, the CTO half-joked: “If Reme gets hit by a bus, we're fucked.” Empowering, right? It's a strange kind of job security.

Short answer: Yes. Cookie-based tracking is dead. Chrome killed third-party cookies in 2024. Safari blocked them years ago. Firefox follows suit. The tracking era is over. But panic selling isn't the answer. Smart brands already moved on. Apple's iOS 14.5 started the funeral. App tracking transparency killed Facebook ads overnight. Billions in ad spend evaporated. Google's Privacy Sandbox tried replacing cookies. Users ignored it. Advertisers couldn't make it work. "Third-party cookies will be deprecated by the end of 2024," Google announced. That deadline passed. The damage is done. Behavioral targeting. No more following users across sites. Retargeting campaigns. Your abandoned cart emails just got harder. Attribution modeling.

Building your own Dynamic DNS (DDNS) server can be a rewarding project, giving you full control over your domain name and its IP address mapping. It's a great way to access your home network resources (like a web server, VPN, or media server) from anywhere in the world, even if your Internet Service Provider (ISP) changes your public IP address. Here's a step-by-step guide to building your own DDNS server, ranging from a simple setup to a more robust, automated solution. Prerequisites A Domain Name: You must own a domain name (e.g., yourdomain.com). A VPS (Virtual Private Server) or Cloud Service: You need a server with a static public IP address that will act as your DDNS server. Services like DigitalOcean, Linode, Vultr, or AWS are good options. A Computer/Device on Your Home Network: Th…  ( 8 min )

In recent years, user interface (UI) design has undergone a dramatic shift with the rise of dark mode. Once seen primarily in code editors or gaming interfaces, dark mode is now available in operating systems, web apps, and mobile applications. But as it gains popularity, a longstanding debate continues: **Light mode or dark mode **which truly offers the best user experience (UX)? This article dives deep into both design systems, exploring their pros, cons, use cases, and what modern research says about their impact on usability, accessibility, and user satisfaction. Light mode, also known as default or day mode, uses a white or light background with dark text and UI elements.

FastAPI is a powerful web framework for building APIs quickly and efficiently in Python. But once your API is public, you’ll want to protect it from abuse. One simple and effective way is using API Keys. In this post, I’ll show you how to set up basic API Key validation in FastAPI. API Keys let you: Identify the client making requests Limit usage (rate limiting, quota) Disable keys without affecting others Secure endpoints behind access controls We'll use FastAPI's dependency injection system to require API keys on specific routes. from fastapi import FastAPI, Depends, HTTPException, Header, status app = FastAPI() API_KEYS = {"123456", "abcdef", "my-secret-key"} # Normally load this from a database or environment def verify_api_key(x_api_key: str = Header(...)): if x_api_key not in API_KEYS: raise HTTPException( status_code=status.HTTP_401_UNAUTHORIZED, detail="Invalid or missing API Key" ) @app.get("/public") def public_endpoint(): return {"message": "This is public"} @app.get("/protected", dependencies=[Depends(verify_api_key)]) def protected_endpoint(): return {"message": "You have access with a valid API key"} You can test it with curl or Postman: curl http://localhost:8000/protected -H "x-api-key: 123456" If the key is valid, you’ll get access. Otherwise, a 401 Unauthorized response. If you're building a commercial API and want to manage API keys, track usage, and set limits without building it from scratch — check out Limitly. It’s a plug-and-play API access manager that works great with FastAPI. This approach is simple and scalable for small to medium APIs. For more advanced use cases, you can: Store keys in a database Add rate-limiting Track usage per key Disable compromised keys dynamically Protect your API early — it’s better than handling abuse later.

Somewhere between learning to write my first "Hello World" and debugging code at 2 a.m., I realized something — I wouldn't be here without the teachers who made me believe I could do hard things. Every year on September 5th, India celebrates Teacher’s Day, honoring Dr. Sarvepalli Radhakrishnan, a brilliant educator and former President who believed teaching was a privilege. He once told his students not to celebrate his birthday but to use it as a day to appreciate all teachers. That’s the kind of humility that sticks. It got me thinking — so many of us wouldn’t be building software, solving problems, or even experimenting with code if we hadn’t met someone along the way who gave us the confidence to try. I remember a teacher telling me once, “You’ll figure it out. You always do.” That sentence has come back to me more times than I can count — especially when my code breaks and I’ve hit my third cup of coffee. And it’s not just about academics. Teachers are the first ones outside our family who actually see us, call us out, help us refocus. They introduce us to ideas and tools that shape how we work and think. Sure, tech moves fast. AI is changing how we learn. But if there’s one constant, it’s the need for someone to guide, support, and inspire us. So this Teacher’s Day, here’s to those who: Gave us confidence before we earned it Image Credit: FreePixel  ( 6 min )

Hey everyone 👋 If you’ve been exploring Terraform — whether in a solo project or a real DevOps team — you might’ve heard things like “backends” and “state locking” thrown around. At first, they sound like internals you can ignore. But once you start working with real-world cloud infrastructure, these two concepts become essential to keeping your deployments safe, collaborative, and disaster-free. Let me break it down the way I wish someone had explained it to me 👇 Terraform keeps track of what it built using a file called terraform.tfstate. 💡 Think of it like a receipt. A backend in Terraform decides where the state file lives. If you don’t set one, Terraform uses a local backend (your laptop). If you’re working on a team, that’s a big red flag 🚩 Because if Bob updates infra on his lap…  ( 7 min )

Hey everyone 👋 If you're working with Terraform and using Git to version your infrastructure code (which you absolutely should!), there's one simple file that can save you from major headaches: ➡️ .gitignore When I first started with Terraform, I was focused on writing .tf files and deploying resources. But I quickly learned that if you don’t handle .gitignore properly, you can accidentally leak sensitive info — and clutter your repo with auto-generated noise. Let me walk you through it the way I wish someone had done for me 👇 You’re moving houses. You label boxes you want to move — clothes, books, tech. But you don’t pack everything. You leave out garbage, pizza boxes, and broken cables. .gitignore is your "Do Not Pack" list for Git — telling it what not to commit. Terraform creates a l…  ( 7 min )

Multithreading is a powerful feature in Java that allows programs to perform multiple tasks at the same time, making them faster and more responsive. This blog post will guide you through everything you need to know about multithreading in Java—from its basic concepts to how to use it effectively in your programs. Multithreading refers to running two or more threads concurrently within a single Java program. A thread is simply a lightweight, independent path of execution. While a process is an instance of a running program, a thread is a smaller sequence of programmed instructions that can be managed independently by a scheduler. The most common use of multithreading is to keep user interfaces responsive, perform time-consuming tasks in the background, or take advantage of multicore proces…  ( 7 min )

Hey DEV community! For the last few months, I've been working on a passion project that I'm incredibly excited to finally share with you all. It started, as many projects do, from a personal frustration. I'm a big fan of the word puzzle game Squaredle, but I found the existing online solvers to be... lacking. I was stuck in a frustrating dilemma: Option A: A solver with an accurate, official dictionary, but a clunky, ad-filled UI that felt like it was designed in 2010 and was barely usable on mobile. Option B: A solver with a modern, slick interface, but an unofficial dictionary that frequently gave wrong answers or missed key words. I thought to myself: "Why can't we have both? Professional accuracy AND a delightful user experience?" So, I decided to build it myself. Today, I'm launching …  ( 8 min )

Managing local virtual machines shouldn't require heavy tooling, brittle shell scripts, or overly complex setups. If you've ever kludged together shell scripts just to boot a test VM, you'll relate.

Normally you can't. But, if you really want, you can. Here is how. Move that block into separate tasklist. E.g. foo.yaml. import it: - import_tasks: foo.yaml. Now, the magic. The content of the foo.yaml - block: - set_fact: count: "{{ count | d(0) + 1 }}" - name: Arbitrary number of tasks here which can fial command: /bin/false ... rescue: - fail: when: count > 3 - include_tasks: foo.yaml How it works. foo is run. set fact set counter to 0 (because there is no counter) your tasks run. If they finish, block finish and everything is good. If any of your task fails, rescue part will be executed. If counter is less than 3, fail is skipped and foo is included. It is the same file as you imported, this is self-recursion. Counter become + 1 Try again. ... If count is too high, fail is executed and recursion stop. If at any count (before fail) block succeed, rescue section finishes, and recursion returns back and it continue to run as it wasn't failed at all (the desired property of the retry).

Show me an architecture no one questions, and I’ll show you a system no one understands. A few years back, I walked into a post-mortem where the architecture was being blamed for everything from latency spikes to the office coffee machine malfunctioning. The architect? Well, he was calm. Unbothered. Certain. “It’s not the design,” he said. “The team just didn’t implement it properly.” There it was: the dead giveaway. He wasn't doubting the design. He was defending it like gospel. Right then, I knew. The most dangerous architect isn’t the one who lacks answers. It’s the one who never asks questions. If you’re an architect or becoming one, doubt isn’t your enemy.

Along the way, I discovered a powerful technique that has completely changed how I work with it, and I wanted to share it. The problem with long chats is that the AI can sometimes forget the specific rules or corrections you've taught it earlier on. You end up repeating yourself, which slows everything down. But what if you could capture that learning and carry it forward? It turns out, you can. When a chat session feels "complete," or if it's just getting too long and slow, you can ask the AI a simple but powerful question: "Based on our entire conversation, please analyze all of my corrections and generate a concise list of 'rules' or 'standing instructions' that you learned." The AI will then proce…  ( 6 min )

1. Meta description rotation for CTR improvement Instead of writing one fixed meta description, I crafted 4–5 variations focused on different triggers: Price & duration: “From €244 · 2h30min ride · Flexible timing · Instant confirmation.” Reliability & comfort: “Private transfer from Venice to Ljubljana · Comfortable vehicles · Door-to-door.” Emotional: “From canals to castles, make the journey smooth and private.” I then tested each on-page using controlled rollouts and monitored how Google picked them up. The combination of bullet formatting (·) and direct value propositions worked best. The landing page had minimal distractions – no intrusive sliders, no auto-play videos. Just: Route info Pricing Vehicles FAQ (accordion block) Booking form The load time was under 2.5 seconds on mobile, which I believe contributed to the drop in bounce rate. Unlike aggressive reindexing, I let this page evolve naturally. First came the meta change, then FAQ schema, then internal links from blog posts and related routes (like Trieste–Ljubljana and Venice–Bled). Only after all changes were in place did I request indexing.

After struggling several months spent brainstorming how I could implement this without DOM patching, something which seemed to be impossible turned out to be pretty easy. Not everything, but essential parts like "remote attaching" of nodes and "PersistentFragment" was achieved purely in conventional Vanilla JS. Here's the tests & playground: https://stackblitz.com/edit/node-group Traditional DocumentFragment is a one‑shot batch—append it once, its children move into the host, and the fragment empties itself. If you need the same nodes elsewhere, you must clone or rebuild them. Group changes that. It holds onto its children as single instances, and lets you attach the very same nodes to multiple hosts - not by duplicating or sequentially reappending, but by moving the live nodes between par…  ( 7 min )

Choosing a Web Application Firewall (WAF) is often a balance between control and convenience. AppTrana offers a managed WAF-as-a-Service with human-assisted rule tuning. SafeLine, on the other hand, provides a fully self-hosted WAF with built-in intelligence. So which WAF is better suited for your team? Let’s compare SafeLine WAF and AppTrana WAF in terms of control, automation, ease of use, and transparency. AppTrana: Security is managed by their team — including rule updates, custom tuning, and threat monitoring. You get convenience, but lose hands-on control and visibility. SafeLine: 100% in your hands. Install via Docker, inspect every log, and manage policies directly. Great for teams that prefer autonomy and transparency.

Just a few small details I tend to apply when finishing WordPress projects. I build mostly with Elementor and JetEngine, so this list comes from that stack. They load an extra JS file from the start. You can remove them with this code or a plugin like Perfmatters. remove_action( 'wp_head', 'print_emoji_detection_script', 7 ); Form plugins often inject CSS globally. I use WP Optimize or Advanced Database Cleaner. Yes, images. But also iframes, videos, and maybe widgets. Reduce the frequency or disable it on the frontend. These aren’t magic bullets, but they help. 🌱 Ellie Miguel – elliemiguel.es  ( 5 min )

Honestly, organizing business logic in Laravel sometimes feels like herding cats. Controllers, jobs, events-everyone's fighting for attention, and before you know it, you've got a mess that's one step away from spaghetti code. Actions and Services to bring structure and clarity. This is an opinionated guideline, based on how my team works - not a universal rulebook. Command pattern rebranded. Actions: Handle full business operations (checkout, registration, import) Services: Reusable, stateless logic (calculation, validation, formatting, API calls, you get it) Naming: Keep it obvious: OrderCreateAction, DeliveryScheduleService with clear, descriptive names Controllers should be on a diet; send that logic to Actions and Services DTOs make your data flow squeaky clean and testable Okay, so h…  ( 10 min )

** 1. Introduction** When you’re using EF Core in production, query compilation can quietly become a performance bottleneck — especially if the same query is executed thousands of times. Normally, EF Core parses your LINQ, generates SQL, and prepares the execution plan every time. The catch? If you’re using the Specification pattern for clean, reusable queries, your repository method probably applies a spec dynamically to DbSet — which makes EF.CompileQuery less obvious to use. In this article, we’ll solve that and show you how to bake compiled queries into your specification-driven repository. 2. Quick Recap: Specification Pattern The Specification pattern encapsulates query logic into reusable, composable units. Example spec for active customers: public class ActiveCustomersSpec : Speci…  ( 7 min )

Storage in Kubernetes Kubernetes offers robust storage mechanisms to manage persistent application data.  A Pod specification defines one or more volumes, specifying their name, type, and mount point. Volumes allow data sharing among containers within a Pod or across multiple Pods with defined access modes. Kubernetes supports various volume types, each suited for specific use cases: emptyDir: A temporary directory created when a Pod starts and erased when it terminates. It's recreated on container restarts, perfect for transient data like caches. hostPath: Mounts a resource (directory, file socket, etc.) from the host node's filesystem. Great for local testing, but avoid in production due to node-specific risks. NFS and iSCSI: Support multiple readers, ideal for shared read-only access.…  ( 10 min )

Hey guys! When I first heard about the term “OpenTofu”, my initial reaction was like, “Wait, what? Food??”. But nope, not anything that we can eat. It is actually related to infra-automation. Yes, the ones that manage cloud resources with code. If you’re familiar with Terraform, you’re halfway there. But what is OpenTofu really? Why people start to talk about it along with Terraform, and why should you care (together with me)? Let's try to do a crash-dive into this together! Terraform, by HashiCorp, has been the go-to tool for Infrastructure-as-Code (IaC). Developers love it because you can: Your infrastructure should be described in code (HCL).

AI-assisted development is often compared to pair programming, but, I think, an equally apt metaphor is a solo tennis match between a developer and an AI model. Instead of playing doubles on the same side, imagine facing the AI across the net. In a competitive yet constructive sparring match: the developer serves prompts, the AI returns code or answers, and together they rally towards a solution. The goal isn’t to defeat the AI, but to outmanoeuvre its unpredictability and guide it toward the right outcome. In this match, a perfectly placed prompt can feel like a swift ace, whereas more complex problems require a longer rally of back-and-forth exchanges. Modern AI coding tools have made these rallies more dynamic than ever. Anthropic’s Claude Code (a powerful CLI-driven coding assistant) s…  ( 13 min )

Introduction If you're starting with PHP, one of the first things you must understand is how variables and data types work. These are the building blocks of any PHP script. In this guide, you'll learn what variables are, how to use them, and the different types of data they can hold. What is a PHP Variable? A PHP variable is a container for storing data. Unlike some programming languages, PHP does not require you to declare the type of a variable. The type is automatically assigned depending on the value you store. Rules for Naming Variables: A variable starts with the $ sign. It must start with a letter or an underscore. It cannot start with a number. It is case-sensitive ($Name and $name are different). Syntax: $variable_name = value; Example: $name = "Alice"; PHP Data Types PHP supports…  ( 6 min )

Types of Operators: Arithmetic Operator Boolean Operator Increment & Decrement Operator Comparison Operator Conditional Operator Logical Operator Arithmetic Operator: Arithmetic operators are used basic mathematical operations. They usually have two operands and one operator. Operators: + , - , * , / , % , ** (10 + 5); // 15 (Addition Operator) (5 - 3); //2 (Subtraction Operator) ("10" + 5); // "105" (string + number → concatenation) JavaScript is a dynamically typed language, so it automatically converts numeric strings into numbers when needed. If you want to manually convert a string to an integer → use parseInt(). (10 * 2); // 20 (Multiplication Operator) (10 % 2); // 0 Modulus (remainder) Boolean Operator: Boolean has only two values: true or false. In boolean value True is 1. In boolean value False is 0. Example: true+1 =2 false-2 =-2 Increment & Decrement Operator Example: Postdecrement:(i--) Example: Preincrement:(i--) Example: i=5; Predecrement:(i--) ** Example: ** Comparsion Operator Example: == Method 5==5 //true "5"==5(In this case it return the true value because it check only the values not the datatypes) === Method "5"=== 5 // false "5"===5 (In this case it return the flase value because it check both the values and the datatypes) Greaterthan Operator & lessthan Operator(>,=,|| OR(||) : If any one condition is true it return true.

Current model predictive control (MPC) approaches for MBS with contact often struggle with computational cost and sensitivity to model inaccuracies. This work introduces a hybrid MPC-Reinforcement Learning (RL) strategy combining established MPC techniques with a learned contact force prediction model to significantly reduce computational burden and enhance adaptation to unforeseen contact scenarios. The proposed methodology demonstrates improved trajectory tracking accuracy and resilience to disturbances compared to conventional MPC and RL control schemes, offering a pathway for real-time cont…  ( 13 min )

🎨 Understanding UX/UI Design Principles as a Frontend Developer As a frontend developer, I’ve always focused on writing clean React/Next.js code, improving performance scores, and debugging broken layouts. But lately, I’ve started diving into something equally crucial: UX and UI Design. I recently began Meta’s Principles of UX/UI Design course (as part of the Front-End Developer Career Certificate), and here’s what I’ve learned so far in the first module — and how it’s already reshaping my mindset as a dev. What is UX vs UI? UX (User Experience) UI (User Interface) How the product feels How the product looks Research, logic, structure Visuals, colors, spacing Empathy + utility Typography + aesthetics UX is all about how usable, intuitive, and helpful the product is. UI is …  ( 6 min )

Introduction Generative AI has moved far beyond basic chatbots. In 2025, successful GenAI applications are safe, responsive, and production-grade from day one. This post will guide you through a proven architecture to build GenAI apps that scale reliably with practical tooling you can start using today. Many developers jump into GenAI by calling an LLM API directly. It works great in a demo but fails fast in production, this is mainly due to: Lack of validation (injections, PII, unsupported formats) No context retrieval (leading to hallucinations) No safety/quality checks No observability or feedback loops A better approach is to adopt a modular blueprint where each step in the pipeline has clear responsibility and is backed by a mature ecosystem of tools. This architecture breaks the L…  ( 7 min )

However, after doing this, I ran into a strange issue: some Python programs (specifically those using dnspython) could no longer resolve domain names. Here's how I diagnosed and fixed the problem. Originally Posted on Ashraful's Blog To route DNS through Pi-hole, I disabled systemd-resolved: sudo systemctl disable --now systemd-resolved My home server then used Pi-hole's IP (e.g., 192.168.10.10) as its DNS server. Most things worked fine — ping, curl, and dig had no issues. But some Python code using dnspython threw an error like: dns.resolver.NoNameservers: All nameservers failed to answer the query Or even: FileNotFoundError: [Errno 2] No such file or directory: '/etc/resolv.conf' Many programs — including dnspython — read DNS server information directly from /etc/resolv.conf.

Have you ever clicked a short link and wondered how it knows where to take you? Short URLs, like those from Bitly or TinyURL, seem simple, but they hide a lot of work. Let's look at how URL shorteners work. What URL Shorteners Do A URL shortener does one main thing: It takes a long URL and makes it shorter. For example, a long Amazon link can turn into something much smaller. When you click the short link, it takes you to the same place as the long one. Handling Many URLs Imagine you are building your own URL shortener. You need to handle millions of URLs every day. Think about these numbers: 100 million new URLs each day Over 1,000 new short links every second Over 10,000 clicks per second Storage How to Make Short URLs How do you make these short URLs?

While going through a course on Scrimba and browsing Reddit, I came across George Pólya’s timeless framework from How to Solve It. Although the book is primarily aimed at solving math problems, as someone whose mind is often full of scattered thoughts, this framework has been a game changer in my problem solving skills when leetcoding or working on projects. *1. Understand the Problem: What it means: Go beyond reading or listening to the problem statement. Try to understand what’s known, what’s unknown, and what you’re being asked to solve, think of any edge cases. *2. Devise a Plan: What it means: Think through your approach before jumping into coding *3. Execute the Plan: What it means: Turn your plan into code, step by step. *4. Look Back: What it means: Reflect on your solution—how well it works, and how it could be improved. What I used to do: Once something worked, I’d call it done and move on. What I do now: I ask myself: Can this be cleaner? More efficient? Could this approach be useful elsewhere? This habit has made me more open to feedback, less attached to my first solution, and more aware of the bigger picture. Following this framework has been a game-changer. Instead of feeling overwhelmed or scattered, I now have a mental roadmap to fall back on something that brings structure and calm even when the problem feels chaotic.  ( 6 min )

As developers, we often spend more time than we’d like doing small repetitive tasks that break our flow — like finding our local IP address, checking if the dev server is running, or trying to connect our phone to Expo. That’s why I built IP-Kit — a tiny but handy macOS menu bar app that helps you access your network info instantly, especially when working with tools like Expo, React Native, Vite, Next.js, or any local server. Here’s what you get out of the box: ✅ Public IP — see and copy your public IP in one click Local IP — quickly grab the IP you need for LAN testing Hostname — useful for network debugging or local setups Auto-refresh — detects changes when switching Wi-Fi networks Smart framework detection — detects active frameworks like Expo, Vite, Astro, etc. Pre-formatted URLs — get your dev URLs ready to scan or copy QR Code generator — instantly create scannable codes to open your dev server on your phone All from your Mac’s menu bar. No need to open Terminal, check your router, or visit sketchy "what’s my IP" sites again. 🙃 This started as a side tool for my own projects, especially when juggling mobile development and testing across devices. I wanted something minimal, fast, and always accessible — without needing to dig through settings or run commands just to find basic info. After refining it a bit more, I decided to polish it up and share it with the community. It’s a small thing, but it saves me time and keeps me in flow — and maybe it’ll do the same for you. This is also my first public app built with Swift and SwiftUI, and it’s been a great learning experience. I’ve loved how quick it is to prototype and build small, clean utilities like this on macOS. Try it out — it’s free IP-Kit is now available on the Mac App Store, completely free. Give it a spin, and feel free to drop feedback or feature ideas — I’d love to keep improving it. 👉 Download IP-Kit on the Mac App Store Thanks for reading — and happy coding!  ( 6 min )

Hi everyone ! Introduction to JavaScript 1. what is JavaScript? interactive and dynamic. web page and CSS styles it, JavaScript adds behavior. runs inside the browser, which means it doesn’t need to be installed separately for users—it just works. 2.Who Invented JavaScript? 1995 by Brendan Eich, a programmer working at Netscape Communications. just 10 days! It was initially called Mocha, then renamed LiveScript, and finally became JavaScript. JavaScript Versions : ES1-1997-First edition ES3-1999-Regular expressions, try/catch ES5-2009-Strict mode, JSON support ES6-(ES2015)-2015-let/const, arrow functions, classes, promises ES7 - ES14-2016–2023-Async/await, optional chaining, nullish coalescing, top-level await, etc. 3.What is the Current Version of JavaScript? , which was released in **June 2024. It includes improvements like: Set methods (like union, intersection) Array grouping New decorators syntax Performance optimizations JavaScript evolves every year, and each version adds useful tools for modern web development. JavaScript Data Types: 1. Primitive Data Types (store single values): String – e.g., "Hello" Number – e.g., 10, 3.14 Boolean – e.g., true, false Undefined – a variable declared but not assigned Null – represents an empty or unknown value BigInt – for very large numbers Symbol – unique identifiers 2. Non-Primitive (Reference) Data Types: Object – key-value pairs Array – list of values Function – reusable blocks of code 4.What are Variables in JavaScript? container that stores data. var – old way, function-scoped -** let **– block-scoped, modern usage const – block-scoped, but value cannot be reassigned Final thoughts: backbone of modern web development, powering everything from simple websites to full-scale web applications. Knowing its history, versions, data types, and variables is the first step toward becoming a skilled developer. Stay curious and keep coding!  ( 6 min )

AWS just rolled out a major upgrade to Amazon CloudWatch — and it’s a big win for centralized logging and DevOps teams across large organizations. You can now automatically enable VPC Flow Logs to CloudWatch across your entire AWS Organization, with flexible scoping and tagging! With the new enablement rules in CloudWatch Telemetry Config, you can: ✅ Automatically create flow logs for existing and new VPCs Entire Organization Specific AWS Accounts Specific Resource Tags ✅ Ensure consistent network traffic monitoring with no manual steps. Let’s say your central DevOps team wants visibility into all production traffic across AWS accounts. Just create an enablement rule that targets all VPCs tagged with: env: production Now, whenever a matching VPC is created, CloudWatch Flow Logs are automatically enabled — no manual setup required. AWS uses Config Service-Linked Recorders to continuously monitor resources. When a VPC matches your enablement rule (tag/account/org scope), it auto-enables logging to CloudWatch. Logs go directly into CloudWatch Logs for immediate visibility. 🔒 Improved Security & Compliance With organization-wide VPC flow logs in CloudWatch: Say goodbye to scattered or missing logs Automatically monitor all relevant VPCs using simple tagging Standardize network visibility across all your AWS environments What do you think about this update? Are you using centralized flow logs already, or is this the push you needed to implement them? Let’s discuss in the comments! 💬👇  ( 6 min )

Context There are two things that can be acknowledged when going over the previous phase. They are goals and features. Now, it comes to the second phase, analysis. In this phase, the tech stack used for development should be determined. Before figuring out the tech stack, the components of this application should be recognized. Usually, a web application would have three parts, namely a front-end application, a back-end application, and a database. In this phase, the tech stack for these three components would become clear. Currently, many websites are developed with React, which is a JavaScript library for web development. It could be an ideal option for this project. However, React does not have built-in tools, like routing and state management. It might make the learning curve steeper…  ( 7 min )

Over the past few months, I’ve been knee-deep in mobile development, not chasing trends, but chasing sanity. My goal? Find the best lightweight framework for building real cross-platform apps without frying my CPU, roasting my RAM, or downloading SDKs heavier than the apps themselves. So instead of the typical fanboy arguments, I actually used all three frameworks: Flutter React Native Kivy ...to figure out which one gets the job done without demanding a space-grade workstation. Here’s the breakdown, battle-tested, brutally honest, and resource-conscious. When I say lightweight, I’m talking about: ✅ Low RAM/CPU usage during dev ✅ Minimal setup time (no 10GB SDKs, please) ✅ Fast learning curve ✅ Doesn’t turn your laptop into a jet engine Framework Language Core Strength Flutter Dart …  ( 7 min )

Problem You are climbing a staircase. It takes n steps to reach the top. Each time you can either climb 1 or 2 steps. In how many distinct ways can you climb to the top? Example 1: Input: n = 2 1 step + 1 step 2 steps def climbStairs(self, n: int) -> int: # if less than or equal to 2 steps, we know there's 1 way or 2 ways. if n end, implementing fibonnaci algoritm n = (n-1 + n-2) for i in range(3, n + 1): step_ways[i] = step_ways[i-1] + step_ways[i-2] return step_ways[n] This problem is basically just the fibonacci sequence, in that to get step 3 upwards, you can take the methods of getting there from the previous two ways and add them together. For example: Think about how you can reach say step 11: If Last step was a single step: So all ways to reach step 10 can lead to step 11 by adding a 1-step jump, so we can add 1 step to all the pre-existing ways to get 10. Last step was a double step: So all ways to reach step 9 can lead to step 11 by adding a 2-step jump, so we can add 2 step to all the pre-existing ways to get 10. note: below n relates to the current step number we're trying to work out: So if we all the ways you got to 10 (n-1) and all ways you got to step 9(n-2) you know all the ways you can get to 11. Cos we can deduce you've got there either by adding 1 or adding 2. So you may have noticed ways = ways(n-1) + ways(n-2) looks familiar, its the same as the Fibonacci sequence Fib(k) = Fib(k-1) + Fib(k-2) Therefore we can simply write this as code -> (i've added comments to explain in code rather than here) As always feel free to drop me a follow on DevTo or twitter/x  ( 6 min )

Problem Given a non-negative integer x, return the square root of x rounded down to the nearest integer. The returned integer should be non-negative as well. You must not use any built-in exponent function or operator. For example, do not use pow(x, 0.5) in c++ or x ** 0.5 in python. Example 1: Input: x = 4 public int MySqrt(int x) { if (x = 2. So we search between 1 and x / 2. Binary Search Mechanics: Pick the middle number mid. Compute mid * mid (cast to long to avoid overflow). If mid * mid == x → return mid (perfect square). If mid * mid x → move right down to mid - 1. Return the last recorded answer because it’s the floor of the square root. By using the Binary Search mechanics, we reduce the numbers needing to be checked can be halved each time, halving the amount of effort needed to find the correct number. As always drop me a follow on DevTo or twitter/x to hear about future articles like this.  ( 6 min )

In most web frameworks (Spring, Django, FastAPI, Axum) the handlers return an object to the framework that will be used to build the response that is sent to the client. However, the Go lang net/http package uses a different approach: the handlers write data directly into the response and have no return value. I believe that this behavior comes from a time that the most frameworks worked with blocking IO and employed optimizations using queues and threads dedicated to process the responses, so your code would return an object describing the response and the framework would put it in the queue to be processed by a thread. With non-blocking IO, there is no need for these optimizations, since the async runtime already takes care of everything related to IO, allowing handlers to write data directly to the response. So, which is better? Return a response or write to the response?  ( 5 min )

Python emphasizes readability and simplicity, making it a great language for both beginners and experienced developers. Open-Source and Free: Python is free to use and distribute even for commercial purposes. Its source code is publicly available, and a vast global community contributes to its development and improvement. General-P…  ( 6 min )

In the era of large language models, prompt size is power — but also a big cost. TokenSpan isn’t a compression library, it’s a thought experiment — a different way of thinking about prompt optimization. Can we reduce token usage by substituting repeated phrases with lightweight aliases? Can we borrow ideas from dictionary encoding to constrain and compress the language we use to communicate with models? This project explores those questions — not by building a full encoding system, but by probing whether such a technique might be useful, measurable, and worth pursuing. A crucial insight behind TokenSpan is recognizing where the real cost lies: We pay for tokens, not computation. So why not reduce the tokens we send, and let the model handle the substitution? §a means "Microsoft Designer" —…  ( 7 min )

🚨 Why This Matters Without governance, your data platform becomes a ticking time bomb. Data chaos isn’t just about bad reports — it’s about loss of trust, wasted engineering hours, poor decisions, and potential compliance nightmares. And in the AI era, the stakes are even higher. If you’re dealing with duplicate sources, unclear ownership, and no clue who should access what — this post is for you. Business users pulling reports from different tools — all showing different numbers Engineers hard-coding sensitive filters into pipelines to "fix" the output Data analysts unsure whether they're allowed to access a dataset — so they just... do Dashboards showing obsolete or wrong metrics Rows with PII data being exposed without control That’s what happens when data governance is absent or treated as an afterthought. Data governance is the set of practices, roles, policies, and standards that ensure your data is reliable, secure, and used appropriately. It's not just about compliance or regulation. It's about control, trust, and scaling your data strategy. Ownership & Stewardship Every table, dataset, or domain must have an owner Owners are accountable for data quality, documentation, and access Empower stewards to maintain metadata, SLAs, and definitions Access & Security Controls Use RBAC (Role-Based Access Control) Enable Row-Level Security (RLS) for multi-tenant platforms or sensitive datasets Manage access centrally — not via code Example: In platforms like Snowflake or Sigma Computing, you can enforce RLS using dynamic attributes like customer_id or region. sql -- Snowflake RLS Example CREATE ROW ACCESS POLICY filter_by_customer AS (customer_id STRING) RETURNS BOOLEAN -> CURRENT_ROLE() IN ('CUSTOMER_VIEWER') AND customer_id = CURRENT_USER();  ( 6 min )

Importing pet accessories into Canada—such as dog collars, toys, grooming tools, and pet beds—requires a clear understanding of the duties and taxes imposed at the border. Whether you're a small e-commerce seller or a pet product distributor, knowing how to classify your goods, calculate fees, and comply with Canadian customs regulations can save you both time and money. When pet accessories cross into Canada, they are subject to two main types of fees: import duties and sales taxes. Import duties are based on the Harmonized System (HS) code classification of the goods, their country of origin, and their declared value.

Introduction If you've been working with ASP.NET Core and haven't encountered Areas yet, you're not alone. Despite being a powerful organisational feature, Areas are often overlooked in tutorials and beginner resources. This oversight leads many developers to create convoluted controller hierarchies and strange architectural patterns that Areas were specifically designed to solve. I've seen projects where developers create "super controllers" or awkward folder structures trying to achieve what Areas provide out of the box. Let's fix that. Areas are a feature in ASP.NET Core that allow you to partition your web application into smaller functional groups. Each area represents a distinct section of your application with its own set of controllers, views, and models. Think of them as mini-MV…  ( 7 min )

What is a Task in Swift? Think of a Task as a box that contains some work your app needs to do. In Swift's async/await world, when you write async functions, you're creating these boxes of work that can run at the same time. func parentFunction() async { // This is the main task (parent) async let child1 = childFunction1() // Creates a child task async let child2 = childFunction2() // Creates another child task await [child1, child2] // Wait for both children to finish } The parent task creates child tasks, and they all form a family tree.

Browser-based load testing verifies the frontend performance of an application by simulating real users using a browser to access your website. This type o testing provides a way to mesure user experience and find issues that are difficult to catch on the protocol level. When running the tests, we will be able to answers questions like: When my application is receiving thousands of simultaneous requests from the protocol-level, what happen…  ( 11 min )

Let's Start from the Beginning About a month ago, the whole vibe coding trend really caught my attention. Everyone was talking about it, everyone. Blog posts were all over the internet, LinkedIn was full of non-technical folks suddenly turning into “builders,” claiming they could create full-blown applications without knowing a thing about software engineering or coding. At first, I didn't pay much attention. I figured it was just another passing trend, like Web3, the metaverse, or Windows Phone (which, to be fair, I actually liked, don't judge me). But then I started seeing even seasoned software engineers showing off their vibe coding setups (I know, it sounds weird), comparing different LLMs and workflows. Then came various posts and articles about predictions about vibe coding repla…  ( 10 min )

With the introduction of Signals in Angular, state management has become much clearer, more maintainable, and predictable. Thanks to primitives like signal(), computed(), and effect(), you can model and derive data effectively while keeping dependencies between different parts of the state under control. However, updating deep values of a Signal is not as straightforward, often requiring manual interventions on the parent state. To address this need, the Angular team is currently developing a new Signal primitive that allows reactive access and modification of deep properties within another Signal: Deep Signal. In this article, you'll explore what Deep Signals are, how they work, and why they can help simplify the code in your Angular applications. Let’s consider an application that manage…  ( 10 min )

lodash It is a JavaScript utility library that is fully compatible with React Native. It provides a large number of helpful utility functions to make working with arrays, objects, numbers, strings, etc., easier and more consistent. Do We Really Need Lodash? Not always. But for more complex operations like deep cloning, sorting, or throttling, Lodash saves time and reduces bugs. Performance Tips Lodash is huge if you import the full library. Always import specific methods like lodash/isNumber to avoid bloating your bundle. because if you do this: import _ from 'lodash'; ✅ It works. ❌ But it includes the entire Lodash library, even if you only use isNumber(). That adds ~70 KB+ to your bundle. Bloating your bundle” means adding unnecessary code that's never used but still included in your final app. Tools like babel-plugin-lodash help optimize it automatically. babel-plugin-lodash This Babel plugin automatically rewrites your imports like this: import { isNumber } from 'lodash'; import isNumber from 'lodash/isNumber'; Final Thoughts Lodash is still useful just use it wisely. Import only what you need and lean on native JavaScript when possible.  ( 6 min )

If you’ve ever wanted to build a SaaS, you’ve probably heard this story: Developer spends 6 months coding a brilliant idea. This happens because most devs build in the dark. They overcomplicate, overengineer, and underlaunch. But 2025 is a different game. Thanks to software as a service in cloud computing, a solo developer can now launch a profitable app in just 10 days — without managing servers, hiring a team, or burning a hole in their wallet. In simple terms: SaaS (Software as a Service) is an app hosted in the cloud, accessed by users through a browser. Cloud computing means someone else handles servers, scaling, and updates — you just build features and collect revenue. Why this matters in 2025: 🚀 Zero DevOps overhead — deploy to Vercel, Supabase, or Render in minutes. 💳 Payments b…  ( 7 min )

Every developer dreams of building something that people actually pay for. The problem? Most SaaS ideas are overbuilt before launch. Most devs spend months coding, polishing, and tweaking… only to see zero customers. And most importantly: They underestimate the speed advantage cloud computing now gives them. If you’ve been sleeping on Software as a Service (SaaS) in Cloud Computing, you’re missing the easiest era to launch. We’re in a moment where one person can create a fully-functional, customer-ready SaaS — from idea to live product — in under 10 days.

What is javascript? javascript is the world most papular programing language and it is easy to learn. javascript is used to create interactive and dynamic web pages. it is responsible for adding functionality to a website and allows for user interaction with the website's content. VARIABLES:- variales are containers for stroing information or data. example var a=10 var b=20 console.log(a+b) output:20 in the above program a and b are variables,10 and 20 are integers. console.log - it is the function in javascript used to print messages or values to the browser's console mainly for debugging purpose. in javascript variable can be declared in 3 ways. var let const using var keyword- function scope or global scope. var x=10 { var y=20 } console.log(y) output:20 //accessible inside the block. using let ketword- block scope. the let keyword introduced in 2015. the keyword must be declared before use. let keyword can not be redeclared. let keyword have block scope. { let a=10 } console.log(a) output Error: a is not defined // a can't be used here becauce a is the block scope. { let a=10 console.log(a) } ouput:20 // a can be used hear. using const keyword- block scope. in javascript the const keyword is used to declare a constant variable. a constant variable once assinged value cannot be reassinged or redeclared. it provide a way to create variable that are meant to be immutable. const a=10 a=20 console.log(a) output Error:assingnment to constant variable. //const cannot be reassinged  ( 6 min )

We already know what JavaScript is, how it was created, and the keywords we can use while programming using this language. Now we’re getting to know our data types, and how we can make use of the ways JavaScript handles them. By the end of this post, you should be able to understand how JavaScript handles values under the hood and you’ll have the ability to tell them apart at a glance… at least that I hope, so let’s get into it! JS has two both primitive and reference types. Primitives types: string, number, bigint, boolean, symbol, undefined, null. Reference types: object, array, function. You can use typeof function to inspect types, though, be mindful that, sometimes, JavaScript can handle types in every way but a logical one.

Hey DEV 👋 I’ve been building a music-focused side project for quite a while now, and I’d love to share it with you all. 🎵 It’s called Bellino — a free music discovery site I built with: React + TypeScript on the frontend PHP + MySQL on the backend A custom REST API for serving dynamic data YouTube IFrame API for embedded playback Bellino lets users: Explore trending tracks and artists Browse curated playlists by mood, genre, or decade Discover albums that were released on this day in music history Listen instantly, with no login required (though creating an account lets you save playlists and favorites) 🌐 Try it here → https://www.belllino.com/home I've been collecting and organizing music data since 2014 because I genuinely love finding great music — both old and new. Most platforms today are heavily focused on current hits or algorithmic recommendations. I wanted something more personal and playful — a place where you could: Discover random playlists and live charts Explore music by vibe, decade, or release date See what albums dropped on your birthday Dive into other users’ playlists and tastes So I built Bellino to scratch my own itch — and maybe yours too. React (TypeScript) – SPA using basic routing and custom hooks PHP backend – lightweight API with fast JSON responses MySQL – for managing users, charts, playlists, track data CSS Modules – no UI libraries, just styled components YouTube IFrame API – for free and simple embedded playback I’m not monetizing this — it’s just a long-running passion project.

Another day in the life of a developer where the code isn't the hardest part to figure out. Morning started simple enough: install Tailwind CSS. Should be straightforward, right? Wrong. Spent half the day battling mysterious "npx" errors that made absolutely no sense. You know that feeling when you're staring at your terminal, questioning every life choice that led you to this moment? Yeah, that was my Monday morning. Finally got Tailwind running, only to realize I had lectures from 9 AM to 4 PM. Missed attendance in one class because sometimes the universe has a sense of humor. Here's where it gets interesting. Remember that ideathon team I mentioned? Turns out they're "a little tooooo busy" to actually work on our project. I was planning this amazing pitch, thinking we'd create something solid together. Instead, I get the classic "let's do it in 2 minutes" approach. The day ended with me hand-washing clothes in the hostel—no washing machine, just pure hand power. But here's the twist: my wrist, which has been bothering me for weeks, actually worked well. The plan? Learn Figma animations, dive deeper into Tailwind, and tackle React Router. Sounds unrealistic? Probably. But when you're working alone, at least you're only disappointing yourself if things don't go according to plan. The real lesson from today: sometimes the biggest debugging challenge isn't in your code—it's in your team dynamics. And sometimes, the best solution is to refactor your entire approach and go it alone. Time to prove that solo doesn't mean lonely in the development world.  ( 6 min )

The query planner optimizes the aggregation pipeline to filter data early and effectively utilize indexes.

Keeping this in mind helps in understanding why an index is employed or not, as the query planner must ensure consistent results across all possible documents in the flexible schema. As an example, a projection renaming a JSON dotted path before filtering can alter its semantics and hinder index usage. I store customer contact information like this: db.custo…  ( 10 min )

Build Your Own AI Agent with MCP: A Developer's Guide to Model Context Protocol Ever wondered how to give your AI assistant access to real-time data, databases, or custom tools? The Model Context Protocol (MCP) is your gateway to building truly intelligent agents that can interact with the world beyond their training data.

JS Operators: Arithmetic Operators: These operators are used to perform basic mathematical operation on numbers. List of arithmetic operators: let x=10; let y=5 let z=x+y; //15 If a string is added with a number, it will produce concatenation. let x="10"; let y=5; let z=x+y; The value of z will be "105". true+1 = 2 b) Subtraction operator (-) : let x=10; let y=5 let z=x-y; //5 In case of any string value [ex "10"] it will change the string value to integer and perform the subtraction. parseInt(): It is a function in JS which is used to convert string to an integer. let x = "10"; let y = 5; let z = parseInt(x) + y; Output is 15. c) Multiplication operator (*) : let x=7; let y=3; let z=x*y; //21 d) Division operator (/) : It gives the quotient. let x=10; let y=2 let z=x/y //5 e) Modulus operator (%) : It gives the remainder. let x=10; let y=2 let z=x%y //0 f) Exponential operator (**) : let x = 5; let z = x ** 2; //25 g) Increment operator (++) : Post-increment: let i=10; i=i+1; //11 It can also be written as let i=10; i++ ; //11 Pre-increment: let x = 5; let y = ++x; log (x); //6 log (y); //6 Pre-decrement: let j=10; --j; log(j); //9 log(--j); //8 Post-decrement: let x = 5; let y = x--; //4 2) Comparison operators: These are used to compare two numbers and returns a boolean value. Ex: let i=5; let j=7; ++i > --j // 6>6 which is false. Logical operators: Multiple conditions can be combined using logical operators. They use logic to return true or false. List of logical operators: log(5 > 3 && 10 > 2); // true b) logical or (||) - returns true if at least one condition is true and returns false only if both conditions are false. log(5 > 3 || 1 > 2); //true log(1 > 5 || 2 > 4); //false c) logical not (!) - The condition becomes reverse like true becomes false, false becomes true.  ( 7 min )

Explore reactive programming before diving into implementation: Introduction: Modern applications demand high responsiveness, efficient resource usage, and scalability. Traditional Java applications based on thread-per-request models often struggle to meet these expectations, especially under high concurrency and latency-sensitive conditions. This is where reactive programming becomes a powerful solution. But before implementing reactive APIs using Reactor or RxJava, it is important to understand why and when this approach is necessary and what problems it aims to solve. This article is for mid-level and experienced software professionals who already have some hands-on experience in building applications and want to understand when and why to use reactive programming.

A Promise in JavaScript is an object that represents the eventual completion (or failure) of an asynchronous operation and its resulting value. It helps you handle asynchronous operations like data fetching, file reading, or timers — without deeply nested callbacks (callback hell). let promise = new Promise(function(resolve, reject) { if (/* success */) { resolve(result); // Success } else { reject(error); // Error } }); Promise States Pending – Initial state, neither fulfilled nor rejected. Fulfilled – Operation completed successfully. Rejected – Operation failed  ( 5 min )

JavaScript Local Storage is a feature that allows you to store data in the user's browser persistently — the data doesn't get deleted when the browser is closed (unlike session storage). Basic Local Storage Methods Store Data localStorage.setItem("username", "Adithi"); Get Data let user = localStorage.getItem("username"); console.log(user); // Output: Adithi Remove a Key localStorage.removeItem("username"); Clear All Storage localStorage.clear(); Store Objects or Arrays Since localStorage stores only strings, you need to convert objects/arrays: let user = { name: "Adithi", age: 21 }; // Save object localStorage.setItem("user", JSON.stringify(user)); // Get object let storedUser = JSON.parse(localStorage.getItem("user")); console.log(storedUser.name); // Output: Adithi  ( 5 min )

This isn't a systematic analysis of StackOverflow's 2025 Developer Survey, it's the random tidbits I found most interesting. (Okay, this was taking way longer than I anticipated, I'm breaking it up into two parts but also, I'm being long-winded. :-P Usually I go back and trim things down but if I don't post this now, I never will). I'd like to see educational degrees split up by area of study. I've been doing this for years and have a B.S. but it's not even tangentially related to coding. It would be great to see these results graphed over time. I appreciate that SO broke out JS and TS as two separate entries, but I'd also love to know what the percentage is when the two are combined. There would be a lot of overlap so it isn't as simple as adding the two percentages together. PostgreSQL d…  ( 9 min )

Java script variables is used to the store data values. Java script uses the keywords likes var,let,const to declare variables. what is var ? Only use var if you MUST support old browsers. The var keyword was used in all JavaScript code from 1995 to 2015. Variables declared with the var always have Global Scope. what is let ? The let declaration declares re-assignable, block-scoped local variables, optionally initializing each to a value. The let keyword was introduced in ES6 (2015). what is const ?

The Fetch API provides a JavaScript interface for making HTTP requests and processing the responses Using the Fetch API With the Fetch API, you make a request by calling fetch(), which is available as a global function in both window and worker contexts. You pass it a Request object or a string containing the URL to fetch, along with an optional argument to configure the request. The fetch() function returns a Promise which is fulfilled with a Response object representing the server's response. You can then check the request status and extract the body of the response in various formats, including text and JSON, by calling the appropriate method on the response. Here's a minimal function that uses fetch() to retrieve some JSON data from a server: Syntax: fetch(url) .then (res=> res.j…  ( 6 min )

As my friends, family, coworkers, and probably several people on the internet already know: I am a AI skeptic – and I’m not particularly shy about it, either. I’m not really sold on the productivity improvement angle, and I’m especially cautious (and critical) when it comes to using it to create content. I’m routinely underwhelmed by emails, blogs, illustrations, logos, and more that were clearly created without human involvement. As an artist and writer myself, those aren’t things that I, personally, am seeking to replace or automate out in my own life. That said, I also work in tech where AI is (for the time being) borderline inescapable. I also think it’s decidedly lame to write something off without giving it a genuine try. And, if I’m completely honest, I was also just plain curious:…  ( 11 min )

When I build software, I try to make the app remember things. So the user doesn’t have to do the same stuff over and over. Most apps reset everything on refresh or when you come back later. That gets annoying fast. Here’s what I mean: You click the same tab again You re-select your filter or sort You retype the same input or prompt You toggle dark mode every single time You expand the same panel again and again It’s small stuff, but it adds up. And it makes your app feel worse. localStorage to remember things I now save small bits of state in localStorage. Just enough so the app feels more stable and consistent.

Lately, I’ve been leaning into building small internal tools for my team. Things that aren’t glamorous, but make our process smoother. One of the most useful was a user interview tracker: just a lightweight web app where we could log interview notes, tag them by feature or theme, and revisit them later. I built it in a few hours using React + Gadget, and it’s one of those tools that quietly changed how we work. Why Build One? I didn’t want to build a whole CRM or research platform. Just a place to: Log interview notes (timestamped and associated with a user) Tag entries by themes (like “onboarding friction” or “mobile nav”) Search and filter by tags or date Keep things private but sharable with the team Enter Gadget: Gadget gives you: Built in Postgres DB (via a visual schema editor) Auth (already wired up) File storage (handy if we want to upload transcripts later) Auto generated REST + GraphQL APIs A backend code editor (runs server side, uses JS/TS) Free tier with generous limits All I had to do was hook up a React frontend, and I was off. A Quick Breakdown of the Build Schema setup Auth API Backend logic What Went Wrong (But Not Really) Nested filtering in GraphQL took a minute to figure out. I wanted to get “all interviews tagged with ‘onboarding’ from the last month” and had to poke around a bit to structure the query right. I briefly messed up the permissions config. My own fault, not Gadget’s and accidentally let anyone delete entries. Luckily, their UI makes it easy to review access rules. Styling took longer than it should have (because I fuss over UI too much). But honestly? Nothing broke. I never got stuck debugging some weird auth middleware or tracking down CORS issues. It felt like working downhill. Final Thoughts It’s simple. And it works. And I actually enjoyed building it.  ( 6 min )

Finding the ideal human resources translation software is critical to the health of your organization. Here’s why. Intelligent internal communication means that your training materials, newsletters, memos and emails all convey the same exact meaning and tone–regardless of an employee’s native language. For this reason, it’s critical to refrain from relying on pure machine translation for HR. If you do, you’ll sacrifice the quality of your workplace communication. And this can affect working relationships, cause misunderstandings of policies and agreements and may even lead to lawsuits. Generally speaking, it may negatively affect your organization’s morale or culture. The problem with using a pure machine translation tool (e.g. Google Translate) as your human resources translation software…  ( 7 min )

I use Asana a lot. I review tasks, leave comments, update timelines, and read through long threads. When I want help from an AI like summarizing updates, writing follow-ups, or planning what is next, I usually have to stop, copy parts of a task into a prompt, and explain the context. I have done that too many times. It always feels clunky and disconnected. Asana MCP fixes this. It connects Claude and Cursor directly to your Asana workspace through Composio, so they can work with your actual tasks, comments, and project data in real time. You don’t need to switch tabs, rephrase anything, or explain what just happened in a thread.

The Funding Rate Arbitrage strategy allows you to profit from the unique mechanics of perpetual futures. For developer-traders, this is a perfect use case for building a custom algorithmic bot. Here's how the strategy works and how you can implement it. The Mechanism: The Foundation of the Strategy Exchanges use the Funding Rate to keep the perpetual futures price anchored near the spot price. Funding Rate > 0: Longs pay shorts. The futures price is trading at a premium to the spot price. Funding Rate < 0: Shorts pay longs. The futures price is trading at a discount to the spot price. Your goal is to take a position that allows you to collect this fee while remaining neutral to the asset's price fluctuations.

While the concept of a selective, multi-engine embedded web framework addresses critical pain points in modern development, the real challenge lies in implementation. How do we make auto-detection reliable? How do we handle engine transitions smoothly? How do we optimize for real-world performance? The answers lie in leveraging modern techniques that go far beyond traditional static analysis approaches. The key to making selective engine loading work reliably isn't perfect detection—it's smart, fast detection with graceful fallbacks.

Monitoring is great, but alerting is what actually wakes us up. In this post, I’ll show how we built a log-based alerting pipeline using Grafana, Loki, and Promtail, running entirely in containers. Yes, alerts triggered from log patterns, not metrics. This approach is especially useful when monitoring behaviors like rate-limiter violations that may not expose traditional metrics. We were facing a challenge: we implemented a rate limiter in Nginx to prevent abuse, but traditional metrics collection (via Prometheus) couldn't capture rate-limit violations (HTTP 429 responses), because those were handled entirely at the reverse proxy level, not within the app itself. The solution? Log everything. Then alert from logs. Grafana Loki Promtail Nginx (with rate limiting configured) Docker Compose…  ( 9 min )

¿A qué nos referimos cuando hablamos de diseño en desarrollo de software? Cuando hablamos de diseño en el desarrollo de software, no nos referimos a dibujar interfaces o hacer diagramas bonitos. En este contexto, diseñar es programar. El diseño se manifiesta en cómo estructuramos el código, cómo distribuimos responsabilidades, cómo nombramos, cómo pensamos en la mantenibilidad, la extensibilidad y la claridad del sistema. Pero también incluye decisiones más amplias como cómo estructuramos el proyecto, cómo organizamos carpetas, módulos y dependencias. El modelado tiene que ver con representar el dominio del problema. Es la forma en que interpretamos y trasladamos el mundo real —o una parte de él— a estructuras que puede entender una máquina. Modelar es preguntarse: “¿Cómo represento …  ( 9 min )

Un poco de contexto En un contexto en el que la inteligencia artificial gana cada vez más terreno, si queremos destacarnos como desarrolladores —y que la IA sea un potenciador de nuestras habilidades y no “algo que nos va a quitar el trabajo”— es fundamental que dominemos las bases y fundamentos del diseño de software. En paralelo, vivimos una época de gran accesibilidad al desarrollo frontend, lo cual es algo positivo. Cada vez más personas ingresan al mundo del código gracias a bootcamps, cursos acelerados y plataformas accesibles. Pero esa misma accesibilidad también tiene un efecto colateral: muchas veces se aprende primero a usar un framework sin comprender las bases que sostienen un software bien diseñado. Y eso genera código que funciona... pero es difícil de mantener, escalar o p…  ( 8 min )

A lot of people grasp new concepts more easily when they’re presented visually—through diagrams or infographics like mind maps. That’s why I’ve decided to share my impressions of Kiro using a few of them. Let’s start with this mind map, which gives a high-level overview of Kiro’s purpose and core features: However for developers, nothing beats hands-on experience. So here’s a mind map showing what an author did when specifying requirements — and what they found as a result. For many, comparing a new technology with an existing one helps bring more clarity.  ( 5 min )

I’ve been working remotely for a while now, and one thing I didn’t expect was how much decision fatigue and miscommunication can mess with your momentum. Coding from home sounds ideal until you realize you’re spending half your time figuring out what the priorities are or waiting on a message that could’ve been a two-minute conversation. So I started experimenting with how I work. Here’s what helped me stay sane and productive as a developer working from home. Clear priorities save hours This structure cuts down on multitasking and gives you a reason to stop over-polishing features that already work. Say more in fewer messages It’s amazing how much faster decisions happen when people understand your intent the first time. Tools don’t solve communication We actually explored some structured approaches to decision-making and planning. One that stood out was Leadership Support. It’s geared more toward alignment and strategy than dev-specific work, but it helped our team communicate better about direction without micromanagement. Takeaway Structure your work Keep your messages clear Choose tools with intention …and most importantly, don’t wait for someone else to fix the mess.  ( 6 min )

Esta serie es mi intento de acercarte conceptos clave de diseño y arquitectura de software aplicados al frontend, especialmente en contextos móviles con React Native.

The Technical Experiment As developers, we often debate AI's impact on our profession in abstract terms. Will GitHub Copilot replace us? Is ChatGPT making juniors obsolete? Instead of another technical analysis, I tried something different: I used AI to write speculative fiction about our augmented future. The result? "The Shadow of Superintelligence: Liberation or a Velvet Cage?" A story that explores Meta's vision of "personal superintelligence" through the eyes of Sarah, a marketer whose AR glasses give her superhuman abilities while her non-augmented colleagues mysteriously vanish.

If you’ve dipped your toes into web development—frontend or backend—there’s a high chance you’ve come across localhost:3000. It’s more than just a port number. It’s the go-to space where development begins, debug logs unfold, and early-stage applications first breathe life. In this blog, we’ll explore why localhost:3000 became a standard, the tools that rely on it, how to troubleshoot it, and how to access it remotely when you're not on the same network. When developers run a local server, it typically listens to requests made to IP address 127.0.0.1, which maps to localhost—your computer. The number 3000 designates the port on which that server accepts connections. So when you visit http://localhost:3000, your browser is reaching out to a web application running on your machine, through p…  ( 8 min )

Unlocking the Power of Edge AI: A New Era for Mobile Applications In today's fast-paced digital world, mobile applications are the lifeblood of our daily interactions, connecting us to everything from social networks to smart homes. Users demand lightning-fast performance, seamless experiences, and, perhaps most critically, ironclad privacy. Meeting these expectations has traditionally relied heavily on cloud computing, where data travels to distant servers for processing before returning to your device. However, this centralized approach often introduces latency, bandwidth strain, and significant privacy concerns. Enter Edge AI. This groundbreaking paradigm shifts artificial intelligence processing from the distant cloud to the "edge" of the network – meaning directly on your mobile dev…  ( 10 min )

As developers, we often gravitate towards the cutting edge: building sleek, high-performance applications leveraging the latest frameworks, cloud services, and device capabilities. Our canvases are vibrant OLED screens, our tools are powerful SDKs, and our users are typically equipped with gigabytes of RAM and blazing-fast 5G. But what if your target user demographic primarily relies on a device with a monochrome screen, a T9 keypad, and connectivity akin to dial-up? This isn't a hypothetical. For millions globally, particularly in emerging markets, the humble feature phone remains the primary gateway to digital services. And for food delivery app development companies aiming for truly universal reach, mastering this domain is not just a business opportunity, but a fascinating engineering …  ( 9 min )

Hey developers! 👋 So I was grabbing coffee yesterday (my 4th cup, don't judge) and scrolling through tech Twitter when I realized something - everyone's talking about the "next big thing" but half of it is just recycled hype from 2019. As someone who's been building stuff on the web since jQuery was considered modern (ouch, I know), I wanted to share the trends I'm actually seeing in real projects, not just conference slides. These aren't just buzzwords - they're things that are genuinely changing how I write code and ship products. Look, I was skeptical about AI coding tools for the longest time. Felt like cheating, you know? But after using GitHub Copilot for six months, I'm not going back to writing boilerplate from scratch like some kind of masochist.

Most engineers don’t struggle because they can’t code. They struggle because someone misunderstood the client—and now everyone’s sprint is on fire. I’m not a developer. I’m a marketer who works closely with product teams building software for real clients. And over the years, I’ve seen one pattern stand out above all: the best software teams don’t just build clean code—they communicate clearly across teams and with clients. This post is adapted from a conversation with one of the tech leads in my company. It isn’t about email etiquette or vague "soft skills." It’s a breakdown of how experienced dev teams handle misaligned expectations, cross-time-zone clients, and shifting requirements—and still manage to keep trust intact.

A few years ago, I was working with a mid-sized e-commerce brand that prided itself on sleek design and user experience. Their website looked flawless on the surface-modern, fast, mobile-friendly. But after one complaint from a visually impaired customer about being unable to navigate the checkout process, everything shifted. They had never even considered accessibility. I’ve been there-on the other side of a user report, scrambling to understand WCAG (Web Content Accessibility Guidelines), trying to comb through code, running manual checks, and realizing just how many barriers exist for millions of users. It’s humbling, even a little embarrassing. But it’s also where the real learning begins. If you're here reading this, you probably know that WCAG compliance isn't just about ticking boxe…  ( 8 min )

Introduction Significant change is taking place in the rapidly evolving field of artificial intelligence, sparking contentious debates on sites like Reddit and Twitter. It appears that the term “vibe coding”, which refers to a relaxed, frequently unstructured method of using AI agents to generate code, is coming to an end. A usage-based, cost-conscious model is quickly replacing what began as an “all-you-can-eat” buffet for developers and aspiring programmers. This shift represents a fundamental reassessment of how AI should support the software development ecosystem, not merely a change in price. With a valuation of $9.9 billion and a reputation as a “poster child” for AI startups, companies such as Cursor quickly rose to prominence and are now among the fastest-growing AI startups.

When I first started writing about tech, Dev.to felt like the right place to be. It was welcoming, developer-friendly, and had a vibrant community. For a long time, it gave me everything I needed to begin: a platform to share, to learn, and to be seen. But over time, as I started thinking more seriously about what I’m building—not just as a developer, but as a creator—I realized I needed something more. Something that felt like home, not just a guest room in someone else’s house. That’s when I started exploring Hashnode. And I’m moving. Here’s why.

Todays article will be a bit different as it will not be purely technical but rather motivational one. I was inspired by it after seeing a following meme on X. It will be about my thoughts on Open Source after doing it for a few years now and how we can all benefit from it. Enjoy! The problem is that we all use Open Source in one way or another but we usually do not give enough credit to people who are maintaining it. We use OS tools either directly - by installing an UI library in our web development project to accelerate development of our new website - or as a dependency for other projects - in this case, we usually are not even aware what packages we are using (good luck scanning full lock.json file :D) In some cases, maintainers are not getting anything for their work apart from ba…  ( 7 min )

As developers, we often get caught up in complex technical challenges while overlooking simpler problems that could benefit from elegant solutions. That's exactly what happened when I discovered the Coast FIRE concept and realized there wasn't a straightforward calculator available online. Coast FIRE is a financial strategy where you save aggressively early in your career until you reach a target amount that will grow (through compound interest) to fund your retirement at a traditional age. Once you hit this "coast number," you can stop saving for retirement and focus on covering current expenses. The math is straightforward, but doing the calculations manually is tedious and error-prone. Most FIRE calculators focus on traditional early retirement scenarios.

One thing that hits you fast when you're building anything beyond to-do apps is this: testing matters. That “everything works on my machine” feeling? Doesn’t mean a thing in production. But here's the thing... testing real dependencies in every test? That’s a pain. Slow tests. External services failing. APIs rate-limiting you. And now your tests are flaky, annoying, and worst of all, unreliable. That’s where mocks come in like the chill friend that helps you focus on your actual code without worrying about the rest of the world blowing up. Let’s paint the scene.

Yesterday I was polishing a Dev.to draft when I spotted something truly bizarre in my Markdown: text The “Filter” Nobody Told Me About What I saw: A raw tag instead of a footnote link. What’s actually happening: A Markdown–HTML filter is supposed to replace these with tidy [1] footnotes… but mine slipped through before that step ran. How I Uncovered It Step 2: Hit “Preview” and spotted the odd :contentReference[…] tag in the live render. Step 3: Traced it to the AI’s citation system—basically a “belt-and-suspenders” audit tool that never meant to show end readers this raw syntax. Why You Should Care Hidden metadata risks. If left unfiltered, you might accidentally expose internal tooling details—or worse, break your own Markdown. Conspiracy fuel? It’s tempting to say “they” are spying on your clipboard. But the real culprit is just a busted filter. TL;DR It exists for audit purposes and should have been auto-removed. If you see it too, add a quick find-and-replace, or fix your rendering pipeline!  ( 6 min )

Currently, if you want to vibe code on your phone, one solution is to use something like VibeTunnel to connect to a terminal-based tool like ClaudeCode or similar. However, typing on a phone is inconvenient, and viewing diffs is not very user-friendly either. I’ve developed a Vibe Coding Telegram bot that allows seamless interaction with ClaudeCode directly within Telegram. I’ve implemented numerous optimizations—such as diff display, permission control, and more—to make using ClaudeCode in Telegram extremely convenient. I think these two features significantly improve the mobile experience: The bot currently supports Telegram’s polling mode, so you can easily create and run your own bot locally on your computer, without needing a public IP or cloud server. For now, you can only deploy and experience the bot on your own. In the future, I plan to develop a virtual machine feature and provide a public bot for everyone to use. chatcode  ( 5 min )

Let me tell you something about NEAR that nobody’s really talking about—not the hype, not the usual "fast and scalable" spiel, but the quiet, almost unfair advantages it’s stacking up while everyone’s distracted by the same old blockchain debates. I’ve been building in this space long enough to see patterns—chains rise, chains fall, and most of them just copy each other with minor tweaks. But NEAR? NEAR is playing a different game entirely. It’s not trying to be Ethereum 2.0 or Solana’s cheaper cousin. It’s doing something… sneakier. And if you’re not paying attention, you’ll wake up one day and realize it’s been ahead the whole time.

But why is that guy from the team next door—who honestly writes messier code than you—suddenly leading the new microservices initiative? Welcome to the brutal reality of tech careers: coding skills get you hired, but they won't get you promoted past a certain point. I've been in tech for over a decade, and I've watched brilliant developers get stuck in senior roles while their less technically gifted colleagues climb the ladder. The difference?

前言 有过 GIS 相关开发工作的朋友都知道，GDAL 是 GIS 图形处理最强大的工具，对于 native 客户端和服务端的开发者来说非常友好，提供了适用于多种 CPU 和操作系统的可执行文件和 lib 文件，只要开发者使用的不是小众平台，都能轻松方便地获取。但对于 GDAL 来讲， Web 就是一个小众平台，并没有提供这个平台的任何支持。所以一般地， WebGIS 软件都会将 GDAL 相关服务部署到服务端，客户端通过 HTTP 请求的方式调用。这个方案有一些不足： 通过网络请求调用增加了应用的响应时间，无法实现实时应用 浪费客户端的算力，增加了服务端成本 所以 WebGIS 用到 GDAL 相关的功能时，总是给用户缓慢、卡顿的感觉。 使用 emscripten + WebAssembly 让 GDAL 应用与 web 应用成为可能：GDAL 是一个 C/C++ 项目，emscripten 是一个用于 WebAssembly 的 C/C++ 编译工具，或许能够使用 emscripten 将 GDAL 编译成 JavaScript 可以调用的形式，从而将这个工具移植到 WebGIS 应用中。 对于习惯于编写 JavaScript 的前端开发者来说，如何开始使用 emscripten 就是一个不小的问题。和大多数开源项目一样，emscripten 也是从源码编译开始。这里不大篇幅赘述安装过程，详细请查看 emsdk 文档。如果安装总是不成功，或者懒得安装，也可以使用 emsdk 的 Docker 镜像。 安装好并验证成功之后，就可以开始尝试使用 emscripten 进行编译了。这里举一个简单的例子： // hello_world.c #include int main() { printf("hello, world!\n"); …  ( 6 min )

🧩 Introduction When we talk about Kubernetes security, most developers think of Role-Based Access Control (RBAC) or Network Policies. But before these higher-level controls come into play, there's a foundational layer that silently ensures every component in the cluster is speaking to a trusted source — mutual TLS (mTLS). In a self-managed Kubernetes cluster, unlike cloud-managed solutions like EKS or GKE, you're responsible for configuring, maintaining, and rotating these certificates. Understanding how mTLS works—and knowing where each certificate lives—gives you deeper visibility into the cluster's internal trust system and can help you troubleshoot or harden your deployment. This post will walk you through: What mTLS means in the Kubernetes control plane Which components use certifi…  ( 8 min )

The application may work based on different databases. Databases use similar SQL syntax, but they offer different implementations. As a result, SQL statements need to be modified, only manually. This involves a huge amount of work and becomes error-prone. Completely automated modifications are nearly impossible. After all, different databases probably offer different functionalities. But an examination shows that most obstacles result from the different syntax of SQL functions. The date and string-related functions, in particular, do not have an industry standard. Different database products have different implementations. To transform string "2020-02-05" to date data, for example, they offer different syntax. ORACLE： select TO_DATE('2020-02-05', 'YYYY-MM-DD') from USER SQL Server： select …  ( 13 min )

STEM — science, technology, engineering, and math — is changing the world we live in. From building apps and curing diseases to solving climate issues and sending rockets into space, STEM is where the future is being shaped. But here’s the thing: women are still hugely underrepresented in these fields. So, what’s holding us back? And more importantly, what can we do about it? Let’s Start with the Facts In areas like AI, cybersecurity, and system design, the number of women is even lower — sometimes under 15%. Many girls lose interest in STEM subjects by the time they reach high school, often because they don’t see enough role models who look like them or because they’re told — subtly or directly — that it’s “not for them.” This gender gap isn't just a diversity problem — it's a missed oppo…  ( 7 min )

And while I love helping, I’ve realized something important: I can’t choose a career path for you and I can't answer same question to 100s of people either. So what did my cute brain suggest? I had the bright idea to put together an article that covers most of the tech fields I know and try to provide as much clarity as I can.

Hey everyone, Rhythm Saha here! I'm the founder of NovexiQ, and as a fullstack web developer, I'm usually deep-diving into the MERN stack and Next.js. But today, I want to pull back from the super advanced stuff for a bit. Let's talk about two fundamental React Hooks that are absolutely essential for *any* aspiring developer, no matter where you are on your journey: useState and useEffect. Honestly, when I first started building components, figuring out when to use useState versus useEffect felt like a real puzzle. It was a common struggle, and I totally get it if you're feeling that way too! But trust me, once you grasp their core purposes, they become incredibly powerful tools in your React arsenal. This post is all about making their differences super clear and showing you how to really…  ( 11 min )

Artificial Intelligence (AI) has become a game-changer for developers, transforming how we code, debug, and deliver projects. AI tools are not just fancy add-ons—they’re essential partners that boost productivity, creativity, and problem-solving. Whether you’re a solo coder or part of a large team, here’s how AI is empowering programmers today. AI-powered coding assistants like GitHub Copilot, Tabnine, or even Grok (yep, that’s me!) are revolutionizing code creation: Code Suggestions: AI generates boilerplate code, function stubs, or entire algorithms based on context. For example, type “create a REST API endpoint” and get a working snippet in seconds. Autocompletion: AI predicts the next line of code, saving keystrokes and mental energy. It’s like having a pair-programming buddy who kno…  ( 8 min )

Meaning Domain Control Validation (DCV) is a process used by Certificate Authorities (CAs) to verify that the applicant for an SSL/TLS certificate is authorized to use the domain for which the certificate is requested. In essence, it's a way for CAs to confirm you own or control the domain before issuing a certificate. This ensures that the certificate, and the secure connection it enables, are issued to the rightful owner of the domain. Benefits Blocks Unauthorized Certificate Issuance It is one of the biggest threats in cybersecurity situations that might involve attackers seeking and acquiring an SSL/TLS certificate corresponding to a domain they do not own. Once a cybercriminal acquires and becomes a trusted level with a certificate associated with a domain, a convincing phishing websi…  ( 6 min )

Reactive Programming with RxJS: A Deep Dive Introduction Reactive Programming (RP) is a declarative programming paradigm focused on data streams and the propagation of change. Think of it as an asynchronous dataflow where changes are automatically propagated through the system. Imagine a spreadsheet: when you change a cell's value, all other cells that depend on it automatically update. Reactive Programming aims to achieve this dynamism and responsiveness in software development. RxJS (Reactive Extensions for JavaScript) is a library that brings the principles of Reactive Programming to JavaScript. It provides a powerful set of tools for working with asynchronous data streams, events, and interactions, making it a cornerstone for modern web and application development. By using RxJS, dev…  ( 8 min )

I had a need to mirror my Android screen to my computer, and I found a really convenient way to do it — using Wireless Display, a built-in feature included for free in Windows. This method allows you to share your mobile screen with your PC without using any third-party apps. Miracast is a wireless technology that allows you to transmit both video and audio from one device to another via Wi-Fi Direct — no HDMI cables or additional apps required. Often referred to as “wireless HDMI”, Miracast supports high-resolution streaming, including 1080p and even 4K, depending on your hardware capabilities. 1. 🟠 Wi-Fi Direct (P2P / Ad-hoc) No router or access point (AP) is required Temporarily disconnects the phone from its current Wi-Fi This is the classic Miracast mode (defined by the Wi-Fi Allian…  ( 10 min )

Cuzzy, let's be real - every time people start shouting about AGI like it's some second coming, I just smile. You'd think the way they talk, there's one massive god-tier AI about to descend from the cloud and start handing out verdicts, replacing jobs, coding startups from scratch, reading your thoughts before your IDE even boots up. But step out of the Twitter thinkpieces, unplug from the hype, and look at what's actually happening in the trenches - dev trenches, real workflows, everyday chaos. What you'll see isn't some singular AI deity. It's a bloody pantheon. I'm talking gods. Plural. Each with its own flavour, its own superpower, its own weakness.

So you're building something cool and need to choose between AWS Lambda and Cloudflare Workers? Been there, done that, got the t-shirt (and probably a few sleepless nights debugging cold starts). Let me save you some time and share what I've learned from wrestling with both platforms in production. Before we dive into the nitty-gritty, let's talk about what makes these platforms fundamentally different. It's not just about branding or pricing—we're looking at two completely different approaches to running code in the cloud. AWS Lambda is like having a really smart building manager. When someone needs an apartment (your function), they either give you an existing one that's ready to go, or they go build a new one from scratch. This can take anywhere from milliseconds to several seconds, dep…  ( 8 min )

API security testing is the process of evaluating the defenses of APIs to ensure they are resistant to vulnerabilities and unauthorized access. It is also now a major part of the software development lifecycle (SDLC), where developers even test the API before they are deployed. Businesses hire cybersecurity companies to perform API security testing to find vulnerabilities or weak points through which attackers can infiltrate the system. As a result, you can know where the security flaws lie and take the necessary steps to fix them. Importance of API Security Testing for Companies The fast growth of digital changes and the widespread use of APIs have led to a new era where systems and services are more connected. However, relying more on APIs also brings new security challenges. Integratio…  ( 7 min )

Welcome to Day 24! Today I explored how to choose between using loops or iterators in Rust and why iterators are preferred in most idiomatic code. I also learned about zero-cost abstractions, an important concept in systems programming that Rust excels at. At first glance, using a traditional for loop might feel more intuitive, especially if you’re coming from C-style or JavaScript programming. But Rust encourages using iterators for a cleaner and more expressive approach. Focus on what needs to be done, not how. Cleaner and more declarative. Less boilerplate. Easier to reason about complex chains of operations. Iterators abstract away common loop mechanics and let you concentrate on the filtering, mapping, and reducing logic. Think of iterators as the Rusty version of chaining methods in …  ( 6 min )

If you think Agile is all about stand-ups and sprints… you're only scratching the surface. Agile methodology that’s laser-focused on writing better code, faster — and it's not Scrum. It's called Extreme Programming (XP) — and it's a game-changer for developers who care about clean code, tight feedback loops, and high-quality software delivery. Let’s dive deep into how XP can upgrade your development mindset — and help you ship better software without burning out. XP is an Agile framework that focuses on improving software quality and responsiveness through frequent releases in short development cycles, which improves productivity and introduces checkpoints at which new customer requirements can be adopted. It was created by Kent Beck in the late '90s, and while many developers know the na…  ( 7 min )

As a long-time Ubuntu user—from 18.04 to 24.04—I’ve always appreciated the system’s stability. However, when it comes to package management, things can become a bit frustrating. For non-repo apps, I often fall back on Flatpak. It has a solid ecosystem, but let’s be honest: it’s heavy, slow to launch, and not exactly snappy for lightweight tools. So recently, I’ve been on the lookout for alternatives. When deepin 25 launched, I noticed they introduced a new package manager called Linyaps. Having been a deepin 15 user in the past, I decided to give it a shot. Installation: Surprisingly Simple Linyaps Website echo "deb [trusted=yes] https://ci.deepin.com/repo/obs/linglong:/CI:/release/xUbuntu_24.04/ ./" | sudo tee /etc/apt/sources.list.d/linglong.list After installation, I tried a few basic apps. The command-line tool ll-cli works similarly to apt, perfect for terminal-savvy users. Linyaps App Store It can also download the app store client. Uninstalling or updating apps can only be done through this client, though. That said, it only seems to have a Chinese interface so far – I couldn’t find an option to switch to English. Maybe that’s still in the works; hope they iron that out soon. Real-World Experience Even after just a few hours of use, Linyaps runs surprisingly smoothly on Ubuntu 24.04. It feels faster than Flatpak and hasn’t shown any compatibility issues so far. Sure, it doesn’t have the massive ecosystem Snap/Flatpak has yet, but for daily use? Definitely worth trying.

I've recently started writing about how I'm building PocketBase.Net in the Building PocketBase.Net Step by Step series. However, I haven't had the opportunity to go over what was already in place. In particular, having a robust testing suite with both unit and integration tests was a very important point for me, as the library could potentially be used by others to manage their data, which is often the most critical part of applications. In this article, I will explain how I set up a working testing environment for my integration tests, using a dockerized PocketBase instance with TestContainers.

Your company just ordered a batch of new laptops, but when they arrive, some of them are different models from those expected. IT updates the inventory, but the records are inconsistent. Some assets are listed by brand name, others by serial number, and a few have no details at all. When audit time comes, everything turns into a scramble. This situation is more common than most businesses realize. With so many devices, applications, and licenses to manage, things can get messy fast if there’s no clear structure in place.

Word Embeddings An assignment of words to numbers is called a word embedding. Consider an example, suppose we have a 2D plane and at multiple coordinates we have some labels like apple, banana, mango are near to each others coordinates, similarly carrot, radish and potato are near each other, and laptop, mobile, TV are far from the vegetables coordinate and fruit coordinate also. Now if we have to place "orange" then think around which coordinates it should be place? It should be placed with fruits, near banana, mango and apple. Words that are similar should correspond to points that are close by. Words that are different should correspond to points that are far away. There is something more to these word embeddings, and it is that they don’t only capture word similarity, but they also c…  ( 8 min )

A backlink is a link created when one website links to another. Backlinks are important for both helping people discover your website and improving your ranking on search engines like Google. Think of backlinks as trust signals or votes of confidence from other websites. The more high-quality backlinks your website has, the more likely it is to rank higher in search results. For example, imagine you run an online bookstore. If a popular blog about reading links to one of your pages, that link becomes a backlink for your site. It not only brings more readers to your store but also tells search engines that your website is credible and valuable.

I originally posted this post on my blog. Pierre started coding back in the 60s and still maintains a 30-year-old codebase. Thanks to the magic of the Internet, and to one of my posts going viral, I've exchanged a couple of emails with Pierre. I don't know him in real life, just on the Internet. His story has captivated me from the beginning. I know only about a few industry veterans, and even fewer who are still actively coding. Since the 60s, Pierre has gone through every boom and hype in this industry. He witnessed the Y2K panic, the birth of Java, the rise of Agile, and probably more that I don't remember now. In one of our emails, I asked Pierre about his take on AI. Today, we only see headlines of CEOs claiming AI generates most of their code, along with headlines saying coders are doomed. But, here's what Pierre, with his wealth of experience, told me about AI (slightly edited for brevity): I'm skeptical about AI. I just don't see automatically generating code from typical imprecise specifications...Apparently we've run out of Internet on which to train AI. It is now feeding on its own hallucinations, like mad cows eating their own prion-riddled offal, or the inbred Hapsburg dynasty. If Pierre, who has seen quite a lot, is skeptical, we shouldn't be worried. I'm not. Pierre reminded me of that joke/meme that we're still safe because AI needs unambiguous and well-written requirements. As long as clients who don't know what they want exist, we're still in business. I don't think AI is taking our jobs anytime soon. Sure, we have to adapt. AI is changing the landscape. For sure, coding in 2034 will look different. Coding today doesn't look the same as coding back in the 70s. We can't ignore AI. AI is like using calculators in math classes. They make us faster, sure, but they can't do the thinking for us.

Mastering the Viewport: An Intro to CSS Media Queries When we create a website, we want it to look good on every device, from a large desktop monitor to a small smartphone screen. This is the core principle of responsive web design, and the key tool for achieving it is the CSS media query. A media query allows us to apply specific styles only when certain conditions are met, such as the screen width. This means we can serve a different, optimized layout to a user on a mobile device without building a completely separate website. It's how a website can "respond" to its environment. Let's look at a simple example. We'll start with a basic layout that works on desktop, and then use a media query to change it for mobile. Our Default (Desktop) Layout /* Styles for screens larger than 768px (the default) */ .container { display: flex; justify-content: space-between; padding: 20px; background-color: #f0f0f0; } .box { width: 30%; padding: 20px; background-color: #007bff; color: white; text-align: center; border-radius: 8px; } This CSS creates a horizontal row of three boxes, perfect for a desktop screen. The Mobile View: Using a Media Query @media (max-width: 768px) { .container { flex-direction: column; /* Stack the boxes vertically */ align-items: center; /* Center the stacked boxes */ } .box { width: 90%; /* Make the boxes wider to fill the screen */ margin-bottom: 15px; /* Add some space between them */ } } This code tells the browser: "When the screen is 768 pixels wide or less, apply these new styles." The flex-direction: column property is the magic that changes our layout from a row to a stack, and we adjust the box width and margin to make it look great on a phone. By using media queries, you can ensure your web applications are not only functional but also provide a great user experience, no matter how a user is viewing them. It's a fundamental step in building modern, accessible websites.  ( 6 min )

This article was originally written and published on Medium on April 10, 2022. I'm migrating some of my favorite posts to dev.to to begin posting new content again. While developing in PHP and Node/React in the past I often dreamily wished I was able to see the servers log output in the browser or JavaScript console. As a newcomer to C#, Blazor and ASP.NET Core I have set myself the goal of familiarising myself with the stack by building a small prototype/feature each week and formalising that knowledge by doing a quick write up in a blog. Yesterday I was hooking up NLog in Blazor and wondering what I should build for my first post and the idea to see if I could make good on my dream of getting server log output into the browser came back to me. “JUST DO IT” We will walk through one appro…  ( 14 min )

What is JavaScript? JavaScript is a high-level,dynamic and interpreted programming language used to make websites interactive. we can use it to control anything like data validation, button functionality,animation updates and more. Every value in JavaScript has a specific type. This type determines what operations can be performed on the value and how it is stored. There are 8 basic data types in JavaScript String Number Bigint Boolean Undefined Null Symbol Object In a programming language, variables are used to store data values. JavaScript uses the keywords var,let and const to declare variables. Only use var if you MUST support old browsers. use let when reassignment is needed Always use const if the value should not be changed Arithmetic Operators Assignment Operators Comparison Operators String Operators Logical Operators Bitwise Operators Ternary Operators Type Operators let str1 = "Hello"; let str2 = "World"; let result = str1 + str2; console.log(result);  ( 5 min )

This document explores the limitations of using useEffect and useState for data fetching in React applications and introduces React Query as a superior alternative. It highlights the benefits of React Query, such as automatic caching, refetching on focus, built-in loading/error states, and smart syncing, which significantly reduce boilerplate code and improve the overall development experience. The document aims to encourage developers to consider React Query for more efficient and maintainable data management in their React projects. The useEffect + useState Struggle For a long time, the go-to pattern for fetching data in React involved a combination of useEffect and useState. It looked something like this: import React, { useState, useEffect } from 'react'; function MyComponent() { co…  ( 7 min )

Problem You need to validate incoming JSON data in POST requests to ensure required fields exist, have correct types, and meet specific criteria before processing. const express = require('express'); const { body, validationResult } = require('express-validator'); const app = express(); app.use(express.json()); // Validation middleware const validateUser = [ body('email') .isEmail() .withMessage('Must be a valid email') .normalizeEmail(), body('password') .isLength({ min: 6 }) .withMessage('Password must be at least 6 characters'), body('age') .isInt({ min: 18, max: 100 }) .withMessage('Age must be between 18 and 100') ]; // Route with validation app.post('/api/users', validateUser, (req, res) => { // Check for validation errors const errors = validationResult(req); if (!errors.isEmpty()) { return res.status(400).json({ success: false, errors: errors.array() }); } // Process valid data const { email, password, age } = req.body; res.json({ success: true, message: 'User created successfully', user: { email, age } }); }); app.listen(3000, () => { console.log('Server running on port 3000'); }); Install express-validator: npm install express-validator express-validator provides middleware functions that validate request data. Each body() call validates a specific field with built-in validators like isEmail(), isLength(), and isInt(). validationResult(req) collects all validation errors. If errors exist, return a 400 status with error details. The validation runs before your route handler, so you always receive clean, validated data when validation passes.  ( 5 min )

I've been developing software for almost 3 decades, and I've lost count of how many brilliant ideas vanished between conception and keyboard. You know the feeling – that perfect solution hits you in the shower, during a run, or right as you're falling asleep.

The results surprised me: I've created 20+ actionable GitHub issues from ideas that would have 100% disappeared within minutes. Here's the truth: It's not about saving time. It's about saving ideas. The Old Reality: Have idea while walking → "I'll remember this" → Open laptop 2 hours later → What was that idea again?

In this article we will show how to develop a Dynamic Array in C and also talk about the advantages and disadvantages of each strategy of memory initialization for arrays. Basic knowledge of programming (logic, etc); C syntax, allocating variables; Memory management in C: pointers, malloc, calloc, realloc, free; An array that can grow or shrink in size during runtime. Unlike static arrays, which have a fixed size, dynamic arrays automatically resize as elements are added or removed. Is it a good idea to start an array with a small size and then realloc it? It depends. If the current memory block can't be extended contiguously, realloc will allocate a new block and copy all n items. Which results in O(n) operation and can cause an overhead.

I'm now writing something about my feeling of posting article on DEV. I have read many of this before, it inspired me to share about my feelings to us. As a beginner, I know that sometimes I don't have many ideas to write about. When I read others word, I can always learn a lot. They tell you the knowledge of programming, but after reading, it is also difficult for me to write something. I just shared one of my projects, it's a simple algorithm. I knew that I don't have many projects to share, maybe sharing some of my feeling, but most of the time I don't know how to write it in words. Some of the feeling can't tell others through words, maybe many of us feel the same, just lack of communication. I just want to write perfect articles, for me, and for everyone. I have been programing for some years, but as a student, I don't have many times to do this. Although I have continue doing this for about 6 years, I'm just a beginner. Programming is not strange to me, but my first article was written in last month. It was my first time to write about my work. I just want to record myself. Although it hasn't been shown to many of others, it is also important to me. It my first post, the first time I try to write something. I'm not perfect in writing articles, but what I need to do is, thinking more, and writing more. Writing needs time and effort, when I write this, I need to think about how to organize my word, how to swich the programming language to natural language. Not just copying and pasting the code, nobody likes it. I want to talk more, but I'm just lack communication. I want to tell many things. I want to talk about my feeling of programing, even how I started writing my first "hello world". It's a long story, just to share it in the future.  ( 6 min )

Introduction: The White Lie Inside Your Computer Look at your computer's system information. If you have a modern processor, you will likely see a number of "processors" or "threads" that is double the number of actual, physical cores inside your CPU. An 8-core processor might report that it has 16 logical processors. A 12-core chip might appear as a 24-threaded behemoth. This isn't a bug. It's a deliberate and calculated deception—a clever white lie told by the hardware to the operating system. This phenomenon, known generically as Simultaneous Multithreading (SMT) and most famously by Intel's trademark, Hyper-Threading, is one of the most successful performance-enhancing technologies in modern computing. It is a trick designed to solve a fundamental problem of efficiency: the fact that…  ( 13 min )

Introduction: The Paradox of Added Complexity It sounds like a recipe for inefficiency: the instructions your software painstakingly sends to a processor are not the instructions that the processor actually executes. Instead of acting on them directly, a modern Central Processing Unit (CPU) subjects these commands to a complex, energy-intensive process of translation and decomposition. It's as if you gave a builder a detailed blueprint, only for them to redraw it into a completely different set of plans before picking up a single tool. Why would hardware designers introduce this seemingly redundant layer of complexity? Why not build a processor that simply does what it's told, one instruction at a time?

While this implementation uses Python, the architectural patterns and SurrealDB integration strategies apply to any language with SurrealDB SDK support. Standard Retrieval-Augmented Generation (RAG) models are powerful but operate on single shot principle: Retrieve then Generate.

Git Branching Branching is a fundamental concept in Git that allows you to work on new features or fixes independently from the main codebase. Each project starts with a default branch (usually main or master), and you can create as many additional branches as needed. Once your work is ready, you can merge your branch into another using a pull request. Branches help you safely test changes, build features, and fix issues without disrupting the main project. Git Reset vs Revert Both git reset and git revert help you undo changes in your code, but they serve different purposes: git reset moves the pointer of your branch to a previous state and can modify your commit history (best used in local branches). git revert creates a new commit that undoes the changes from a previous commit, pres…  ( 7 min )

Computer science is a huge field, spanning web dev, systems engineering, AI, and more. It’s super easy to dive into high-level stuff like building apps or websites with modern tools and frameworks. But that ease means a lot of people skip the low-level basics. How computers actually work, how code becomes machine instructions, or what’s happening in the hardware. Knowing this stuff, like memory management or how the CPU and OS interact, gives you a deeper edge. You’re not just coding—you understand why things work or break. The industry pushes quick results, and focus on job-ready skills, so the low-level foundations often get ignored. But grasping what we are doing is what makes us a better developer. Your enthusiasm for relearning computer science as a self-taught enthusiast is infectious! Diving deep into the world of computer science is thrilling, but the complexity of how computers work can feel daunting. So, how do we tackle this? How do we unravel the intricate layers of a computer’s inner workings and build a solid understanding from the ground up? But common we are devs; we work with complex systems everyday. Alright, so how are we going to do this? The answer has been right in front of us all along: books. There are countless books we could follow, but I’m going to focus on the one i am reading. "The Elements of Computing Systems" - Noam Nisan and Shimon Schocken. It is a fantastic resource I discovered while browsing the internet. tackling every problem from the ground up in a beautifully clear and engaging way. I’ll soon share updates on my progress with this project, detailing my learnings and celebrating the joy of engineering. Thanks for reading! Note: I am also a beginner, trying to learn. So if you have something for me to learn. Contact Me!  ( 6 min )

Ever glued together socat, raw JSON, and a prayer just to talk to QEMU from Go? I did—until one missing comma killed an overnight CI run. So I bolted a Go backend onto QEMU’s own QAPI generator, and now every VM call is type-safe, fully async, and always in sync with upstream. ➡️ Check out the project on GitHub QEMU already ships a rich JSON interface (QAPI), yet Go developers still end up: Writing raw JSON by hand – easy to mistype, hard to test. Chasing partial wrappers – most cover only “common” commands. Fixing silent schema drift. Fully typed bindings for every command, struct, and enum in qapi-schema.json. Async events & requests via goroutines and channels—no polling loops. Transport helpers for QMP, QGA, serial pipes, TCP, stdio… the lot. Schema-sync guarantee – regenerate on eac…  ( 6 min )

If you've been building with LLMs for a while, you've probably experienced that moment when the model feels like it's more of a hindrance than a help. Worsening quality of answers, constant reminders to start a new chat window, and constraints that continually get forgotten. These are all symptoms of what happens when the models context starts to get too polluted. When building ai agents these problems can be the difference between having a reliable production ready agent and having a system that works great in your local tests but breaks in production. To bridge this gap and have a consistently reliable agentic system, you need to know how to effectively manage context. This is where context engineering comes into play and is essential for reliable agent building at scale. Before we dive …  ( 9 min )

LeetCode 1: Two Sum Problem: Given an array of integers nums and an integer target, return indices of the two numbers such that they add up to target. You may assume that each input would have exactly one solution, and you may not use the same element twice. You can return the answer in any order. public int[] TwoSum(int[] numbers, int targetSum) { var numberToIndex = new Dictionary(); for (int currentIndex = 0; currentIndex < numbers.Length; currentIndex++) { int currentNumber = numbers[currentIndex]; int requiredNumber = targetSum - currentNumber; if (numberToIndex.ContainsKey(requiredNumber)) { return new int[] { numberToIndex[requiredNumber], currentIndex }; } if (!numberToIndex.ContainsKey(currentNumber)) { numberToIndex[currentNumber] = currentIndex; } } throw new InvalidOperationException("No solution exists for the given input."); } Instead of checking every pair with a nested loop, we can use a dictionary to remember the numbers we’ve seen as we scan the array, storing the value and its index. We loop through each number, and subtract it from the target. If the result exists in the Dictionary, we know we've found our two numbers and can return the indexes of these numbers. But wait how does result = target - currentNumber give us the two numbers? Well, because if we can't find a match we still add the currentNumber to the Dictionary, so we keep a record we've seen that number somewhere in the array. Target is 20; result = 20 - 7 = 13 index of 13 and index of currentNumber and Bingo we have our two numbers. Well, simply because all paths in a code base need to return a result. However, instead of returning [0,0] which is wrong, we throw an exception to show we've handled all paths, but wasn't a valid outcome.  ( 6 min )

Java Records, finalized in Java 17, provide a concise way to create immutable data carriers. But what happens when your clean Record needs to validate its data? Suddenly, that elegant one-liner becomes a validation challenge. Let me show you three approaches to Record validation I've encountered in production code, and why I ended up building a new solution. Consider this simple user registration scenario: public record User(String name, String email, int age) {} Clean, right? But in production, you need validation: Name: 2-50 characters, not null or empty Email: valid format, not null Age: 0-120, reasonable range Suddenly, your elegant Record isn't so simple anymore.

Apple’s product pages are great examples of clean design, subtle animation, and precise typography. Inspired by this, I set myself a challenge: could I recreate the AirTag landing page and present the process in under ten minutes? The result is a pixel‑perfect build using React (Vite) and Tailwind CSS, documented in an eight‑minute speed‑run video. The official AirTag page opens with the tagline “Lose your knack for losing things” and uses simple sections like: “Ping it. Find it.” “Precision Finding” “Get by with a little help” (apple.com/airtag) These elements make it a great UI challenge—minimal content but high polish. Scaffolding – Bootstrapped a Vite + React + TypeScript project and added Tailwind CSS. Figma – Created a layout in Figma inspired by Apple’s page and exported the assets. The Figma file is included in the repo’s figma folder. Components – Each section (hero, feature cards, CTA) is a separate React component. Tailwind utility classes handle spacing, and typography. Speed‑run video – I recorded the build process and condensed it into a fast-paced video that runs just over eight minutes. 🎬 Watch the 8‑minute build video 💻 Browse the code on GitHub Utility‑first styling speeds things up – Tailwind let me prototype quickly without leaving the markup. Figma is a great source of truth – Having a pixel‑perfect reference meant less guesswork. Feedback is invaluable – I’m eager to hear from other front‑end devs—how would you enhance this? Maybe add animations Improve accessibility Refactor the component structure? Feel free to share feedback in the comments or submit pull requests!  ( 6 min )

Right now I’m: Researching how to implement this automation Thinking about the market potential if I made it modular or separate Sometimes the best ideas come from casual conversations. I'll keep you posted if I decide to build it out. And if anyone here has experience with monetizing small automations: Drop your tips below! Thanks for reading, Jonathan (0xj0n1)  ( 5 min )

RuneScape has been around for over twenty years but the private server community is still growing. In fact it feels more active now than ever before. Private servers or RSPS let players enjoy the game in new ways. Some servers offer faster leveling. Others have custom bosses or completely different content. What used to be small projects with bugs and missing features have become stable games with big player bases. So what is driving this growth One reason is better tools. Developers now have access to more open source server files and better client emulators. Setting up a server used to take weeks. Now it can be done in a day. Some developers have even added their own systems like raids or skill trees from scratch. Another big reason is mobile gaming. More people are playing games on their phones so RSPS owners are starting to think about mobile support. A few servers already run well on Android and more are working toward that. AI tools have helped too. Some RSPS developers use AI to help write quests or fix bugs faster. This saves time and keeps players engaged with fresh content. Promotion is also easier now. There are websites that list and rank servers so players can find active ones quickly. One of the most updated sites is rsps100.com where you can browse top servers by votes or activity. If you are a developer or even just curious about game design RSPS is a great space to explore. You can learn about multiplayer systems economy balancing and player feedback all in a live environment. Private servers are not just copies of the original game anymore. They are creative projects shaped by both nostalgia and modern tools. And they are not slowing down anytime soon.  ( 6 min )

Solana Hold Your Funds, Redeem Them Now? As a developer coming from the Ethereum blockchain, where I've built numerous apps, one key difference I noticed is that Ethereum accounts do not require specific storage for tokens. Your wallet address handles everything native ETH, ERC20 tokens, and NFTs. However, after diving into Solana development for nearly two years, I’ve discovered something unique and worth discussing: rent on Solana. What is it, and can you get it back? Let's explain it in simple terms. On Ethereum, the ecosystem revolves around three main types of tokens: Native ETH: Used to pay for gas and governance. ERC20: Fungible tokens for projects like stablecoins or utility tokens. NFTs: Unique, non-fungible tokens for digital collectibles or assets. When you create an Ethereum …  ( 8 min )

Overview In this post, we’re going to talk about what exceptions are and how to handle errors in a Java project using @ControllerAdvice. We’ll go over creating custom exceptions and sending back the right HTTP status codes. By the end, your API will be easier to maintain, more reliable, and give your users clearer error messages. Let’s start with the basics: what’s an exception? Trying to access a file that doesn’t exist. Dividing by zero. Our always friend, NullPointerException. When an exception occurs: Java creates an exception object with details about the error. The regular flow of the application stops. Java tries to find a matching handler to deal with the exception. There are two main types of exceptions: Checked exceptions → Must be either caught or declared (e.g., IOException).…  ( 6 min )

Veo 3 is a powerful video generation model by Google Deepmind, which was originally available through Vertex (Google Cloud). Now available with Google Gemini Pro, it can be used with limited access. The usage is limited to 3 videos per day and also the video that can be generated is 8 seconds. Though the numbers are very small, it can be fun to experiment with it. Here are some of the prompts that I tried with this video generation: For the initial attempt, I went with one of the traditional concepts using a cat and it was good. A kitten playing guitar in a street For the next one, I tried to get a video of screen recording/sharing of a code editor with some Python code. Even though the specifications are mentioned in the prompt, the video that was generated by the model wasn’t very accurate with respect to the specifics. A screenshare video (macOS — Visual Studio Code Editor) of typing a Python code (code for factorial of a number) without any audio It was able to create the title for the video very specific to my description in the prompt but not the video :) The above examples are with the mode of Text-to-Video. Additionally, you can try to create a video with an image input (something like Image-Text-to-Video) with the prompt to the model. This is still limited to the 8-seconds video length restriction. This video generation model can also be accessed via Gemini API on a paid-preview basis (more details on the official documentation page). Try out some of your own prompts and play with the model.

As organizations adopt microservices architecture and Kubernetes for deploying containerized applications, one critical question arises: “How do external users securely access my services running inside the Kubernetes cluster?” By default, Kubernetes provides service types like ClusterIP, NodePort, and LoadBalancer to expose applications. However: ClusterIP only allows internal access. NodePort exposes your app on every node's IP and a static port — not ideal for production. LoadBalancer provisions a cloud provider load balancer — but one per service, which is expensive and harder to manage at scale. Imagine a production app with: A frontend UI service A backend API service An admin dashboard A metrics endpoint If you use LoadBalancer for each, you’ll quickly rack up cloud costs and lose c…  ( 8 min )

Language models have become surprisingly capable at many tasks, from writing code to answering complex questions. But there's a troubling phenomenon lurking beneath their impressive performance: hallucinations. These aren't the mysterious visions of science fiction, but something far more mundane yet equally concerning—AI systems confidently generating information that simply isn't true. At its core, an LLM hallucination occurs when a model generates content that sounds plausible and coherent but is factually incorrect, nonsensical, or completely fabricated. Think of it as the AI equivalent of someone confidently telling you that Napoleon won the Battle of Waterloo or that there are 14 months in a year. The information flows smoothly and convincingly, but it's fundamentally wrong. The phen…  ( 9 min )

Most people understand the basics of what git is. add, commit -m "please work", push. Well, having this for a git workflow makes it feel like a burden more than a tool. Lemme expand your mind a little bit. Imagine your code like a story one you're telling to your future self or another developer joining you. Every commit is a chapter, every branch is a plot thread, and every merge is where storylines converge. When viewed this way, Git transforms from a mundane version control system into a powerful narrative tool that makes your development journey coherent, traceable, and beautiful. A well-crafted commit message is like a good book title it tells you exactly what to expect inside. Instead of cryptic messages like "fix stuff" or "updates," consider commits as documentation of your thought…  ( 8 min )

⚠️ This article was translated by AI. Click here to read the original version in Portuguese. In large-scale system development, the quantity and complexity of microservices can become a formidable enemy. After facing this enemy multiple times, I refined a set of architectural patterns. These patterns are the foundation of an approach I call Gateway-Oriented Architecture (GOA). GOA doesn't propose new components, but rather the disciplined organization of consolidated patterns to achieve maximum productivity and security. Gateway-Oriented Architecture (GOA) aims to simplify microservices development by isolating security and communication complexity into specialized components called Gateways. Instead of having each microservice handle authentication, authorization, routing, and public ex…  ( 7 min )

Among the various search algorithms, Linear Search stands out as the most fundamental. In this article, we will delve into the workings of Linear Search and break down its implementation step by step. Linear Search is a simple search algorithm that examines each element in a list one by one until it finds the desired element or reaches the end of the list. It doesn't need the data to be sorted. Let’s use the array below as an example and say we need to search for the number 63. The algorithm will first check the first element, 80. The index pointer will ask: “Is 80 the number we need?” The algorithm responds: “No, it’s not!” The index pointer moves to the next element, 14. The pointer asks, “Is 14 the number we’re looking for?” The algorithm replies, “No.” It will then move to the nex…  ( 8 min )

This isn't just a nice-to-have anymore—it's table stakes for modern enterprise systems. Zero-downtime architecture is the art and science of designing systems that remain operational during updates, maintenance, and even partial failures. It's about creating resilient systems that can evolve without interrupting the user experience. But let's be…  ( 13 min )

Recently I experimented with Cognito secured AWS API Gateways and came across an annoying problem - how can I test my application end to end without having to log in to Cognito with a Browser? Removing the Cognito Authorizer for testing purposes would be one option, but there are cases where applications make use of the tokens for access control or other mechanisms and changing the application behaviour with regards to tokens just for tests doesn't seem be right. Fortunately, CDK supports custom AWS resources that can be used to create dummy users with all the attributes necessary! First, we define a Lambda that backs our API.

Lately I’ve been trying to get more consistent with my Linux workflow — not just using it, but actually understanding what’s going on under the hood. While looking for practical, no-fluff resources, I came across this site that really clicked with me. It’s not overwhelming or packed with ads; just clean, focused content. There’s a section called the Linux Library that I’ve bookmarked already. It breaks down commands, concepts, and tools in a way that feels like a cheat sheet you’d actually use. Whether you’re brushing up on your terminal skills or exploring new tools, it’s super handy.

In recent months, the term vibe coding has gained traction — generating code with the help of AI, iterating quickly until you get something that works. Does it work? Yes, especially for problems that are widely documented on the internet.

The field of software engineering is undergoing a profound transformation, driven by the rise of Artificial Intelligence (AI), Machine Learning (ML), and Large Language Models (LLMs). What was once a discipline grounded in rigid processes and strict team roles is rapidly evolving into a more dynamic, intelligent, and automated ecosystem. From Traditional Teams to Intelligent Orchestration Enter AI and LLMs. Today, with the advancement of technologies like Model Coordination Protocols (MCP) and AI-driven development assistants, many of these roles are becoming partially or fully automatable. We’re no longer just writing code — we’re architecting systems that write, test, review, and even debug themselves. The MCP Engineer: A New Role in the AI Era Here’s how the process unfolds in this new paradigm: The engineer feeds high-level product requirements into the system. An LLM generates UI/UX mockups based on user personas and product goals. Another model creates a development plan, breaking the work into frontend, backend, and integration tasks. AI agents write code, generate API specs, and build responsive UIs. Test suites are auto-generated and executed, including edge cases. Documentation is produced as the system understands what it built. The product is deployed via automated CI/CD, and monitored using AI-powered observability tools. Throughout this process, the MCP engineer supervises the automation — identifying failures, debugging AI misinterpretations, and refining prompts or training data. Why This Matters It’s not about replacing creativity with code generation — it’s about scaling creativity across the stack. The Future Is Collaborative Intelligence Engineering, in its modern form, is becoming less about typing lines of code and more about orchestrating intelligent subsystems — like a maestro guiding a symphony where each instrument is powered by AI.  ( 6 min )

Tagasaurus is a privacy-first media-manager that lives entirely on your desktop. Drop photos, videos, GIFs, PDFs, or audio files into the app and Tagasaurus builds a fully local library you can search like magic. Type a natural-language description ('sunset over the vacation 2019', 'college picnic 2012') or let the camera roll: Tagasaurus can find every shot of your old friend Jack by comparing face embeddings even if you never wrote a single tag. Because everything runs offline, none of your memories ever leave your machine. It can handle storing audio, pdfs, gifs and video. https://github.com/mantzaris/Tagasaurus/ Under the hood the app is a tight Electron JS bundle with a modern Svelte 5 + Routify frontend. The renderer is written in TypeScript with runes-based reactivity and Tailwind-style utility classes, while the main process handles heavy lifting in Node. Media ingest pipelines lean on fluent-ffmpeg (pointed at statically bundled ffmpeg/ffprobe binaries) to extract thumbnails, duration metadata, and frames for face detection. Faces are embedded with an ArcFace ONNX model; text search uses a lightweight sentence-embedding model—both executed through onnxruntime for fast, CPU-friendly inference. Vectors, file hashes, and canonical paths land in a libSQL (SQLite) database, giving you ACID guarantees and blistering full-text + nearest-neighbour queries without shipping a server.

Introduction I had heard about OAuth2 many times, but I never really understood what it was, since I had never worked on implementing authentication and authorization myself. Before we jump into OAuth2, let's review some basic terminology you should know: is the step that you verify the identity of the user. verifying who you are Authorization is the step that you verify the permission of the user. verifying what you're allowed to do What is OAuth2? OAuth2 is a security standard that allows one application to access user data from another application on the user's behalf without needing the user's password. For example, when you log into a website using your Google account, OAuth2 allows that website to access your data without seeing your password. Many o…  ( 7 min )

The Role of AI in DevOps: Explained Simply with Examples DevOps is a way of working that helps developers and IT operations teams build, test, and release software faster and more reliably.

## Diferenças de Ciclo de Trabalho: Fluxo Contínuo vs. Sprints A forma como as equipes organizam seu trabalho impacta diretamente a produtividade, a qualidade e a capacidade de adaptação a mudanças. Duas abordagens comuns são o fluxo contínuo e os sprints, cada uma com suas particularidades. Vamos mergulhar nas diferenças entre elas, com exemplos práticos. Fluxo Contínuo: O Rio que Corre Sem Parar No fluxo contínuo, o trabalho flui de forma ininterrupta, sem períodos fixos para planejamento ou entrega. O foco está em: Entrega constante: Novas funcionalidades, correções de bugs e melhorias são implementadas assim que estão prontas. Flexibilidade: Adaptações às mudanças são feitas em tempo real.

PostgreSQL is a powerful, open-source object-relational database system known for its robustness, extensibility, and standards compliance. You must have a Linux server (like Ubuntu). You must have admin rights (called sudo). You must know how to use the terminal/command line.

If your site is even a little bit successful, you’re probably being hammered by traffic from “OpenAI,” “Googlebot,” or “Bingbot” — or so your logs claim. Spoiler: most of it is fake. Here’s how I learned that the hard way, what I did about it, and the exact steps to fix it. I run a site that gets about 20,000 legit visits per day. But my server logs? 500,000+ “bot” requests every 24 hours — mostly claiming to be “OpenAI” or “Googlebot.” Analytics showed almost none of that traffic. But my server load was spiking, and then my AdSense dashboard dropped this warning: Crawler – Unknown Error Restricted Ad Serving Your site is blocking our ad validation bots, so we’re cutting your revenue. User-Agent headers are worthless for bot detection — anyone can spoof them. So I built an integration …  ( 6 min )

If you are familiar with Oracle Database, you know the basic INSERT INTO command. Let me briefly remind you of its traditional usage with some simple examples: SQL> CREATE TABLE vahid.tbl ( id NUMBER, name VARCHAR2(100), last_name VARCHAR2(100) ); Table created. SQL> INSERT INTO vahid.tbl VALUES (1, 'VAHID', 'YOUSEFZADEH'); 1 row created. SQL> INSERT INTO vahid.tbl (name, last_name) VALUES ('VAHID', 'YOUSEFZADEH'); 1 row created.

Meilisearch is a really powerful search engine; it’s fast, open-source, and easy to set up. But if you don’t configure it properly, especially the indexing and attributes, it can start to feel slow. Let’s say you set up an index with a few thousand records and start running searches. At first, things feel snappy — queries respond in under 20ms, which is very fast. But then you notice that some searches — especially those with 3 or more keywords — are suddenly taking above 300ms or more, even on a local instance. Making just a few small tweaks to how you set up your indexes and attributes can significantly improve speed and overall performance. Have you ever felt like your Meilisearch results are a bit slow? Maybe you’ve had to wait longer than expected for a simple search to load. In many …  ( 10 min )

The first real backend decision I made on Learnflow AI wasn’t about speed, performance, or even voice logic. It was about simplicity. From the start, I knew two things: Every user should be on a plan (Free or Pro) Every plan should define exactly what features the user could access But here’s the problem: Most tools split these concerns across two completely different services. One API for auth. Another for billing. A third for usage tracking (usually the database). You end up stitching together logic just to answer a question as basic as: "Can this user start a session right now?" Learnflow AI isn’t a typical SaaS app. It’s usage-based, voice-powered, and session-restricted. And to make the experience smooth, I didn’t want 5 lookups across 3 APIs. So I made a bet: What if billing and acce…  ( 8 min )

THINGS I’VE WORKED ON/COMPLETED… The Find method in BST. The levelOrderForEach in BST. In the levelOrderForEach method, I wasn’t entirely sure ‘how much’ should go into the callback (what to put in the callback v the main method, but I realised that if I created the array in the callback, that this would not work as a new array would be created each time. I asked for some advice about this and was told that it was perfectly acceptable for the callback to perform a simple task (console logging nodes visited in this case). I tried to implement recursion in the levelOrderForEach method, but struggled with it - someone suggested to me that recursion might not be the best way to approach BFS, so I went with the iterative approach in the end.

Hey Devs, Dhruv Here. 👋 I've been building software and writing content about it for about 7 years now. I’ve witnessed the evolution of tooling — from writing repetitive code manually to having AI pair-programmers that feel almost magical. 2024-2025 has been a whirlwind for agentic AI. We're not just getting code suggestions anymore — we’re delegating entire tasks to AI-powered agents. In this post, I’m sharing 10 AI agentic tools that I personally find game-changing — the kind that save time, reduce context switching, and let me focus more on architecture and less on boilerplate. Quick detour for clarity — agentic tools are not just passive assistants like autocomplete or chatbots. These are task-completing, goal-oriented AIs. You give them intent (“write tests for this module” or “gener…  ( 7 min )

In my Task Automation API, I added email notification support using Python’s smtplib. The setup is minimal, uses no extra packages, and leverages environment variables to securely manage SMTP credentials. Here’s a breakdown of the implementation, inspired by this commit: View commit on GitHub import smtplib from email.mime.text import MIMEText from email.mime.multipart import MIMEMultipart import os def send_email(recipient: str, subject: str, body: str): sender = os.getenv("SMTP_SENDER") password = os.getenv("SMTP_PASSWORD") smtp_server = os.getenv("SMTP_SERVER") smtp_port = int(os.getenv("SMTP_PORT", 587)) msg = MIMEMultipart() msg["From"] = sender msg["To"] = recipient msg["Subject"] = subject msg.attach(MIMEText(body, "plain")) with smtplib.SMTP(smtp_server, smtp_port) as server: server.starttls() server.login(sender, password) server.sendmail(sender, recipient, msg.as_string()) To keep secrets out of the codebase, define these in your .env file or server environment: SMTP_SENDER: Your email address SMTP_PASSWORD: SMTP password or app-specific password SMTP_SERVER: SMTP host, e.g., smtp.gmail.com SMTP_PORT: Port number, usually 587 How I Use It After a user schedules a task, once and it’s validated, I call send_email to notify them: send_email( recipient=current_user.email, subject="File Upload Successful", body=f"Your file {file.filename} was uploaded and verified." ) No external dependencies Secure configuration with environment variables Easy to extend for HTML emails or attachments later Adding SMTP email with smtplib is a lightweight, effective way to send notifications in your FastAPI app. This pattern fits nicely in automation workflows like mine.

AI Copilot or Job Killer? Microsoft's New Report Details the Future of Work In a landmark new report, Microsoft has shed light on one of the most pressing questions of our time: how will generative AI reshape the job market? The tech giant, a key player in the AI revolution, has analyzed the skills and tasks most susceptible to automation. The findings suggest not a simple story of replacement, but a complex evolution where adaptability will be paramount, moving beyond hype to provide a data-driven look at the roles facing the most significant transformation. According to the analysis, roles characterized by repetitive, predictable tasks are most exposed to AI's influence. This is less about entire professions disappearing overnight and more about specific functions within them being automated. Key areas identified include office and administrative support, where tasks like scheduling and data entry are prime candidates for AI assistants, and customer service, where chatbots can handle routine inquiries, freeing up human agents for more complex issues. However, the report emphasizes that this disruption is a double-edged sword. Microsoft frames AI primarily as a "copilot" designed to augment human capabilities, not eliminate them. The key takeaway is a call for a massive shift in workforce skills. The roles least at risk are those that rely heavily on uniquely human traits: critical thinking, complex problem-solving, emotional intelligence, and creativity. The future of work, as envisioned by Microsoft, is one of human-AI collaboration. The challenge now lies in reskilling and upskilling the workforce to thrive in this new, augmented reality.  ( 7 min )

Hey developers! 👋 Today I want to share some insights about the reset statement in Uniface ProcScript - a handy little command that can help you manage function values effectively. With some assistance from AI, I've put together this quick guide based on the official Uniface 10.4 documentation. The reset statement is pretty straightforward - it resets the value of a specified ProcScript function to 0 (FALSE). Think of it as a way to clear or reinitialize certain system functions when you need a fresh start. reset ProcScriptFunction For example: reset $procerror Parameter Data Type Description ProcScriptFunction Literal The ProcScript function you want to reset The $status variable will contain: <0: Reset cannot be used with the specified function 🚫 0: Function was successfully reset ✅ Good news! You can use reset in all component types except: Self-contained Reports 📄 Services 🔧 Here's a real-world scenario where reset comes in handy. Let's say you're working with form modifications: operation exec city = "New Orleans" ; this sets $formmod to 1 reset $formmod ; reset the modification indicator edit NAME end In this example: We modify the CITY field, which automatically sets $formmod to 1 🏙️ We then reset $formmod back to 0 using the reset statement 🔄 Finally, we edit the NAME field 📝 Remember that reset can only be used with functions that specifically support this feature. Always check the documentation for the particular function you're working with! The reset statement might seem simple, but it's a powerful tool for managing state in your Uniface applications. Whether you're dealing with error indicators, modification flags, or other system functions, knowing when and how to use reset can make your code cleaner and more predictable. Happy coding! 🚀 This article is based on the official Uniface 10.4 documentation.  ( 6 min )

(Първо публикувано на 20.01.2017) Днешният алгоритъм е доста интересен и всъщност доста ме плашеше преди време. 😀 Това е един от най-популярните алгоритми за сортиране и е широко използван в практиката, тъй като е подходящ за големи списъци от данни. Това е Quicksort! Погледнете обяснението за QuickSort в AlgoList — голяма част от информацията в този пост е взета от там (страхотен сайт с много добри обяснения за редица популярни алгоритми). ОПИСАНИЕ: Quicksort е алгоритъм за сортиране от тип “разделяй и владей” (разделяме задачата за сортиране на по-малки и накрая обединяваме малките решения в едно голямо). Както казахме, Quicksort е най-подходящ когато искаме да сортираме големи списъци от данни. Средната му сложност е O(n log n), а в най-лошия случай е O(n²), макар че в повечето случаи…  ( 10 min )

JavaScript is a programming language used to make the web pages interactive. It can update and change both HTML and CSS. Data Handling: In JavaScript, it refers to collect,store, process and manipulate data. JS Data types: Big int: It is used for storing big integer values in javascript [Ex:123456789012345678901234567890] In Java,data types can be divided into two groups: primitive and non-primitive. Primitive data types: Identifiers: It is the name which is given to the variables,function,arrays etc. How to declare variable in JavaScript: let name="Vidya"; In Java, the variable can be declared as: string name="Vidya"; Statically typed programming language: If a variable has to be declared, data type must be declared before defining the variables. Dynamically typed programming language: In this, no need of mentioning the type of variable when declaring it.The type is automatically decided at runtime, based on the value assigned. var: It is a keyword used to declare a variable in JS. There are two types of scopes : local scope and global scope. Local scope: In this, a variable can be accessed only inside a specific part of a code like a function. Global Scope: If a variable is declared outside any function using var, it becomes globally scoped i.e, it can be accessed from anywhere in the code. In Java, redeclaration cannot be done, but reinitialization can be done. let: It offers block scope, which means the variable exists only within the {}. let name=John; const: It is used to declare a variable whose value cannot be changed once the value is set. const i = 10; // Error Here, error will occur because a variable declared with const cannot be changed after its initial value is set.  ( 6 min )

While perusing my Masters of Computer Application in Gurugram, I’ve been preparing for coding interviews. It’s been hard but very rewarding. I wanted to get into the tech industry as a full stack web developer, so I decided to step up my study plan by following the famous NeetCode 150 questions list. This list is a carefully chosen set of questions that will help people get ready for software interviews at top tech companies. Why I Picked the NeetCode 150? NeetCode 150 is a full but easy-to-use playlist for anyone who wants to get better at data structures and algorithms. It includes the classic “Blind 75” list and 75 more handpicked questions. It covers all the important topics and groups problems into three levels: Easy, Medium, and Hard. This lets you learn strategically and gradually improve your skills. My Progress So far Learning Highlight: Knowing the ins and outs of two-pointer techniques and recursion has really changed how I solve problems. Some days are hard, especially after a long day of lectures and homework, but sticking to a schedule (my goal is 10 questions per week) keeps me going. Tracking the percent of completion helps you see how far you’ve come and keep going. Doing the code solutions by hand: Reading the NeetCode solution is helpful, but actually writing the code yourself is what really helps you understand. Concentrate on Weak Areas: Are you having trouble with a problem? Put it aside for a week and then look at it again. Stay on track: Even solving one or two problems a day adds up quickly! Don’t Compare Your Progress: Everyone’s path is different. Some days you’ll solve a lot of problems, and other days you’ll only solve one. That’s fine. Happy coding ;-)  ( 6 min )

🚀 Tracking My First 4 Real Users — Lessons from Week 1 of Biz Tracker Hey devs 👋, I’m Prasoon — a 16-year-old developer from India. A few weeks ago, I launched my first real product: Biz Tracker, a browser-based stock and billing web app built for small businesses and indie founders. Since then, I've started seeing real users — not thousands, but enough to start learning. Here’s what my Umami dashboard showed in the last 24 hours: 👥 Total Visitors: 4 📈 Views: 11 🧭 Visit Duration: 3m 2s average ↩️ Bounce Rate: 25% 📱 Devices: 75% Tablet, 25% Mobile 🌍 Countries: 75% India 🇮🇳, 25% United States 🇺🇸 🔗 Referrer: vercel.com Even more interesting — users explored beyond just /stock: /map /about That’s real engagement 👀 Time spent matters more than traffic count People stayed for over 3 minutes — that tells me they’re not just clicking, they’re actually trying the tool. Low bounce = good first impression 25% bounce rate is solid. My landing flow might be working. Curiosity is validation Someone checked /map and /about. That means they were exploring — I should prioritize improving those next. Tablets dominate I designed Biz Tracker to work on mobile, but 75% used tablets. Time to fine-tune tablet experience too.

When you're learning about databases, one concept you'll hear often is the foreign key. At first, it might sound a bit technical, but don’t worry—I'll explain it in a simple way, with examples, so it sticks. A foreign key is a column (or a set of columns) in one table that refers to the primary key in another table. Think of it as a link or relationship between two tables in your database. ✅ It helps keep your data connected and consistent. Imagine you have two boxes: Box 1: A list of countries with unique IDs (Primary key) Box 2: A list of people, where each person belongs to a country To know which country each person is from, you store the country ID from Box 1 inside Box 2. That country ID in Box 2 is a foreign key. Let’s say we have two tables: countries table CREATE TABLE countr…  ( 6 min )

GORM is one of the most popular Object Relational Mappers for Go. It provides a clean, expressive API for interacting with databases, abstracting away much of the boilerplate SQL code while still allowing fine-tuned control when needed. To start using GORM, first install the library: go get -u gorm.io/gorm go get -u gorm.io/driver/sqlite # or another driver like mysql/postgres Then, set up a simple connection: import ( "gorm.io/gorm" "gorm.io/driver/sqlite" ) db, err := gorm.Open(sqlite.Open("test.db"), &gorm.Config{}) if err != nil { panic("failed to connect database") } You define your data structures as Go structs. GORM uses reflection to map these to database tables: type User struct { gorm.Model Name string Email string } Create: db.Create(&User{Name: "Alice", Email: "alice@example.com"}) Read: var user User db.First(&user, 1) // find user with ID 1 db.Where("name = ?", "Alice").First(&user) Update: db.Model(&user).Update("Email", "new@example.com") Delete: db.Delete(&user) Productivity: Less boilerplate, cleaner code. Portability: Works with multiple databases. Flexibility: Lets you drop down to raw SQL when needed. Slightly larger binary size. May not be the fastest for high-performance use cases — consider raw SQL or sqlx if needed. GORM is a great tool for building Go applications that need reliable database interaction with minimal friction. It’s especially useful for rapid development, small to medium-sized apps, and teams looking for readability over raw performance.  ( 6 min )

This is a submission for the Redis AI Challenge: Beyond the Cache. I built a location-aware prayer time web app that delivers three core features: Mosque-Specific Display Each mosque has a unique URL that shows its daily prayer schedule, name, address, and date. The times are accurate based on its stored latitude and longitude. Browser-Based Location Detection When users visit the general homepage (https://redis-prayer-times.netlify.app), the app detects their location using the browser’s geolocation API, fetches their latitude and longitude, and then displays prayer times specific to their location. Nearby Mosque Finder This makes it easy for both mosque administrators and everyday users to access accurate prayer times tailored to their precise location. 🌐 Live Website: General: https://redis-prayer-times.netlify.app Mosque-Specific: Example: Masjid Istiqlal Nearby Mosques: https://redis-prayer-times.netlify.app/nearby-mosque How I Used Redis Cloud This project uses Redis Cloud beyond caching in the following ways: Each mosque's coordinates (latitude, longitude) are stored in Redis using GEOADD, with their mosque ID or name as the key. When a user's location is detected via the browser: The app executes GEOSEARCH to find the nearest mosque(s) within a certain radius (e.g., 5km or 10km). If a nearby mosque is found, the app uses its exact location to fetch the corresponding prayer times. The mosque’s name and address are also displayed to the user.

“The most scalable systems separate responsibility — and memory.” Modern enterprise systems demand scalability, auditability, performance, and clarity in design. This is where CQRS and Event Sourcing shine. Let's explore what they are, the problems they solve, when to use them, and when not to. CQRS stands for Command Query Responsibility Segregation. It’s an architectural pattern that separates read and write operations into different models. Commands: Change system state (e.g., createOrder, updateUser). Queries: Return system state (e.g., getOrdersByUserId). Instead of using one data model for both, CQRS proposes distinct models — one optimized for writes (commands) and one for reads (queries). Event Sourcing is a pattern where state changes are stored as a sequence of events, not just a…  ( 7 min )
